As I posted on the newsgroup:
It sounds like standard crash dialogs are disabled on your system (or the
problem somehow manifests differently for you). But the cause is the same.

Never mind, it only happens when you don't use -g.

Here's more issues, this time the sample tries to write to a file handle that
was opened in read-only mode:
import std.stdio;
import std.file;
void main()
{
foreach (string entry; dirEntries(".", SpanMode.shallow))
{
auto file = File(entry, "r");
string[] lines;
foreach (line; file.byLine)
{
lines ~= line.idup;
}
foreach (line; lines)
{
file.writeln("asdf");
}
}
}
$ dmd test.d && test.exe
Nothing is outputted. But with -g:
$ dmd -g test.d && test.exe
$
std.exception.ErrnoException D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\stdio.d(1164):
(No error)
So without the symbolic info I get nothing in stdout. However If I change the
sample to this:
import std.stdio;
import std.file;
void main()
{
foreach (string entry; dirEntries(".", SpanMode.shallow))
{
auto file = File(entry, "r");
file.writeln("asdf");
}
}
$ dmd test.d && test.exe
object.Error: Access Violation
..
and this error message will loop forever.
But with -g I only get one error message as it should be:
$ dmd -g test.d && test.exe
$
std.exception.ErrnoException D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\stdio.d(1164):
(No error)
So I'll just have to compile with -g all the time until this gets resolved.

The range error is 'entry' is a string, and you are slicing it beyond it's end.
This is not a bug in the compiler or runtime, it's in your code.

This is not a bug in the compiler or runtime, it's in your code.You have misunderstood the bug report. The problem is that, to the user, the exception was silently discarded 2.054. In reality, the range exception results in an uncaught SEH exception. On most machines, it will cause the standard "Program has stopped working" dialog, however Andrej has those dialogs disabled. With DMD 2.058, it causes a barrage of Access Violation errors. This is a bug, as the correct behavior is to print the stack trace of a RangeError and exit. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

I've run into this issue yet again. And I've noticed something: If I compile
with '-g' then I get the exception thrown. Otherwise nothing is thrown and I
get back an exit code: -1073741819
Here's an example with Vladimir's AE library:
Use this test.xml file:
<Class file="somefile"></Class>
And this script:
import ae.utils.xml;
import std.path;
import std.file;
import std.stream;
import std.stdio;
void main()
{
foreach (string entry; dirEntries(".", SpanMode.shallow))
{
if (entry.extension == ".xml")
{
Stream stream = new BufferedFile(entry);
XmlNode document = new XmlDocument(stream);
auto node = document.children[0];
writeln(node.attributes["file"]);
writeln(node.attributes["none"]);
}
}
}
Notice that "file" will exist but "none" does not, and this should throw a
RangeError.
So if I run 'rdmd -g test.d', I get:
core.exception.RangeError test(20): Range violation
and a stack trace.
But if I run 'rdmd test.d' (without -g) I get the exit code '-1073741819'. I
can't even catch the error by using Throwable, it simply exits the app
altogether.
As it stands using dirEntries is completely unreliable for me, and this issue
keeps shooting me in the foot because I keep forgetting about it as I
innocently use the foreach loop without thinking.
And here's a way to force the range error without using -g:
import ae.utils.xml;
import std.path;
import std.file;
import std.stream;
import std.stdio;
void main()
{
string[] entries;
foreach (string entry; dirEntries(".", SpanMode.shallow))
{
if (entry.extension == ".xml")
{
entries ~= entry;
}
}
foreach (entry; entries)
{
Stream stream = new BufferedFile(entry);
XmlNode document = new XmlDocument(stream);
auto node = document.children[0];
writeln(node.attributes["file"]);
writeln(node.attributes["nonexistent_key"]);
}
}
So basically the only safe way of using dirEntries is to save a list of files
and then do another foreach loop to process it.
I really hope we get this fixed. :/

Did you notice that the return code -1073741819 is 0xC0000005, which usually
means "Access Violation"?
I guess this is happening in the stack trace generation code that is executed
when an exception is thrown. This code is expensive, has to deal with
non-existing or buggy debug information and is unsafe itself. I recommend
disabling it by default.
I usually run this early from a shared static module constructor to disable it
(including always loading dbghelp.dll and debug symbols at startup):
extern extern(C) __gshared ModuleInfo
D4core3sys7windows10stacktrace12__ModuleInfoZ;
void disableStacktrace()
{
ModuleInfo* info = &D4core3sys7windows10stacktrace12__ModuleInfoZ;
*cast(typeof(info.o.ctor)*)(cast(void*)info + 8) = null;
}

The problem seems solved with 2.059 Win32.
I can see the errors with or without -g.

It may not be solved, but I think that keeping a bug open with no up to date
repro is pointless. By all means, let's reopen the bug if a repro is found
again, but until then, I think it's reasonable to close this.
