Summary: OPTLINK ruins the day yet again
Product: D
Version: future
Platform: Other
OS/Version: Windows
Status: NEW
Severity: regression
Priority: P2
Component: Optlink
AssignedTo: nobody puremagic.com
ReportedBy: nfxjfg gmail.com
Compile the following source code with dmd x.d -g
OPTLINK will crash:
Unexpected OPTLINK Termination at EIP=0041338F
EAX=6F733231 EBX=6F733231 ECX=00000000 EDX=1D8CC66F
ESI=0033FE7C EDI=1D8CC66F EBP=0033FED4 ESP=0033FD60
First=0042000
(copied by hand)
It doesn't crash without -g. It doesn't crash when you reduce the number of
template instantiations, or reduce the references to instantiated templates
(you can vary these by changing the numbers in the program).
Bug 3870 is probably the same bug, but I can't possibly know (the register
contents are completely different).
The test case works perfectly fine on Linux.
---- this is file x.d:
template Tuple(T...) {
alias T Tuple;
}
template Repeat(int count) {
static if (!count) {
alias Tuple!() Repeat;
} else {
alias Tuple!(count-1, Repeat!(count-1)) Repeat;
}
}
void sometemplate(int T)() {
foreach (x; Repeat!(62)) {
sometemplate!(T)();
}
}
void main() {
foreach (x; Repeat!(298)) {
sometemplate!(x)();
}
}

d-bugmail puremagic.com http://d.puremagic.com/issues/show_bug.cgi?id=4009 Funny thing: if I name _exactly_ the same file x2.d, OPTLINK doesn't crash! copy x.d x2.d dmd x.d -g -- OPTLINK crashes dmd x2.d -g -- OPTLINK doesn't crash Let me repeat: this bug is not reproduceable if you change the filename. Makes me wonder what the flying fuck is going on. (Maybe I should mention that I did this under wine on Linux, but I also had someone reproduce the crash on a real Windows.) -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

I think it has something to do with module names being part of symbol names.
When you change the file name the symbol names change as well.
FWIW, my development branch of QtD (compiled with dmd 2.042) doesn't link on
Windows. This bug may be the cause.

In dmd 1.060, the example above doesn't crash anymore, but this does:
------- x.d
template Tuple(T...) {
alias T Tuple;
}
template Repeat(int count) {
static if (!count) {
alias Tuple!() Repeat;
} else {
alias Tuple!(count-1, Repeat!(count-1)) Repeat;
}
}
void sometemplate(int T)() {
foreach (x; Repeat!(320)) {
sometemplate!(T)();
}
}
void main() {
foreach (x; Repeat!(498)) {
sometemplate!(x)();
}
}
-------
wine dmd x.d -g

ESI=0033FE7C EDI=65D474DD EBP=0033FED4 ESP=0033FD60
First=00402000
There's lots of similarities in the test case and register dump, so I suppose
it's the same bug.

Does anyone know what Walter thinks about this?
When can we expect a fix?
Same question. This bug(or a similar one) has been a pain for building QtD on
Windows. It occurs or it doesn't depending on some unrelated factors.

I can reproduce it, it appears to be related to the -g switch. The object file
is very large, it perhaps is caused by a counter overflow.

I haven't tested against this very example, but your latest patch also seems to
fix a crash at a different EIP I've been getting since the last few days (repro
too large):
EIP=00425343
EAX=0001B04C EBX=00000202 ECX=00000004 EDX=01160000
ESI=0043B544 EDI=01164000 EBP=0012FFF0 ESP=0012FF7C
First=00402000
If this is true and not just a random magical arrangement of electrons and
planets, I might arrange a little party tonight O_O
Much appreciated!

http://d.puremagic.com/issues/show_bug.cgi?id=4009 03:28:45 PDT --- The overflow would happen when some of the data structures exceeded 128K in size. I checked the other seg faults for optlink in Bugzilla, but those apparently have different causes. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
