rdmd main.d leads to Segmentation fault

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?

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 > > Can you compile a dub project? 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. ?
