digitalmars.D - Tracking down bug: Need a few precompiled 32-bit linux Hello Worlds

reply "Nick Sabalausky" <a a.a> writes:
Twice now (from two totally different projects) I've come across precompiled 
linux binaries that give me "Illegal Instruction", but they work when I 
compile them myself. The idea of shared-lib/libc issues has been looked 
into, but it doesn't seem to be the culprit. Both times, D1 and Tango were 
involved. So I suspect it's something in Tango, but before I take this to 
the Tango team I'd like to be more sure. For all I know, it could be a D1 
thing, or even something backported over from druntime, something else, etc, 
I don't know.

I don't have a machine with a modern enough CPU that I can reproduce the 
offending binaries myself, so I'd appreciate if someone could build a few 
hello worlds for me:

1. D1/Tango
2. D1/Phobos
3. D2/Phobos

// d1tango.d
import tango.io.Stdout;
void main()
{
  Stdout.formatln("Hello");
}

// d1phobos.d and d2phobos.d
import std.stdio;
void main()
{
  writefln("Hello");
}

I'd need them built on a relatively modern CPU, I'd guess that anything that 
supports 64-bit and/or multi-core will probably do. They need to be 32-bit 
binaries. And to avoid any shared lib compatibility issues (which seem to be 
common on linux), they should be built on something like Ubuntu 10.06 (or 
older) or CentOS 4 (or older), etc (Building in a VM would be fine of 
course).

I'd appreciate anyone that has the right setup and can spare the bother to 
help out with this.

A C or C++ one might be good too, in case it's not even a D issue at all 
(like maybe the GCC linker?).


 // d1tango.d
 import tango.io.Stdout;
 void main()
 {
  Stdout.formatln("Hello");
 }

 // d1phobos.d and d2phobos.d
 import std.stdio;

Nevermind, I was able to borrow someone's laptop and install a VM. If 
anyone's interested, it looks liek it is (somehow) a problem in Tango, and 
the ticket is here: http://www.dsource.org/projects/tango/ticket/2061
