Hey,

simple hello world crashes with segfault:

import std.stdio;
void main()
{
    writeln("hi");
}

$ rdmd main.d
Segmentation fault

Same problem with a vibe.d project.

Just set up this VirtualBox


$ dmd --version
DMD32 D Compiler v2.078.1
$ rdmd --version
rdmd build 20180121
...
$ uname -a
Linux timoses-home-debian 4.9.0-4-686 #1 SMP Debian 4.9.65-3+deb9u1 (2017-12-23) i686 GNU/Linux


$ dmd main.d
$ gdb ./main
(gdb) r

Any ideas?

Where did you get the D toolchain?
Does the same segmentation fault happen with dmd or gdc or ldc? (dmd should be the more probable)

Can you compile a dub project?

What `disas` command shows at the point of failure?

Got it from here:
http://d-apt.sourceforge.net/
with

$ apt-get install dmd-compiler

> Does the same segmentation fault happen with dmd or gdc or ldc? (dmd should be the more probable)

dmd: generated executable also leads to segfault
gdc: works...
ldc: didn't try

$ gdc --version
gdc (Debian 6.3.0-18) 6.3.0 20170516

No, leads to executable causing a segfault as well


So, it does compile, but compiled executable with dmd seems to cause segfault.

How would I do that?

$ (gdb) info line main
No line number information available for address 0x431c24 <main>
$ (gdb) info line 0x431c24
Function "0x431c24" not defined.

?

I can not reproduce this.

Well, the cause is not yet uncovered, I suppose...

Any more ideas?

Sometimes such crashes can be caused by files left from previous installation. Or maybe confusion between gdc and dmd files.

Thanks!

I did

$ gdb main
$ (gdb) set logging on
$ (gdb) r
$ (gdb) disas

Output:

Helps?
