D.gnu - Can't catch Phobos exceptions
- Demetri (22/22) Mar 17 2014 I wrote a small D program. When compiled with DMD, it works fine,
- Iain Buclaw (3/25) Mar 17 2014 SIGABRT is normally a sign of an assert(false) in release code in GDC.
- Johannes Pfau (4/22) Mar 17 2014 The example works fine here (with exactly the same parameters).
- Demetri (3/25) Mar 17 2014 I have GDC 4.8.2, 64 bit
- Demetri (2/29) Mar 17 2014
- Demetri (2/24) Mar 17 2014 What does gdc -v show on your system? That may help.
- Iain Buclaw (3/30) Mar 18 2014 On my work system, the last time I built gdc was around 2014/02/21.
- Demetri (5/41) Apr 01 2014 Sorry everyone!
I wrote a small D program. When compiled with DMD, it works fine,
but neither GDC nor LDC2 can catch exceptions thrown from Phobos
(proven by GDB). How do I fix this?
Example code:
import std.process;
void main(){
try
{
spawnProcess(["/dev/null"]);
}
catch (Throwable p)
{
return;
}
}
which dies with SIGABRT when compiled and executed, even though
the catch block should catch the ProcessException.
Compiler: ldc2 based on LLVM 3.3 and DMD 2.063.2 (invoked via
ldmd2 -O -inline -release), but also happens with gdc 4.8.2
(invoked via gdmd -O -inline -release). The execption is caught
when I use dmd -O -inline -release to compile, even when I only
catch ProcessException and not Throwable.

SIGABRT is normally a sign of an assert(false) in release code in GDC.
Try running a backtrace on the application.

The example works fine here (with exactly the same parameters).
Do you have a recent GDC? 32bit/64bit?

I have GDC 4.8.2, 64 bit Should I upgrade to 4.9?

I tried reinstalling GDC, but this test faild with GDC 4.9 On Monday, 17 March 2014 at 20:20:24 UTC, Demetri wrote:I have GDC 4.8.2, 64 bit Should I upgrade to 4.9?
