Hello,
when I try to run following code:

import std.stdio;
import std.net.curl;

void main()
{
	writeln("dlang.org");
}

I get following error:

Fatal Error while loading '/usr/lib/x86_64-linux-gnu/libphobos2.so.0.64':
	The module 'std.regex' is already defined in './maina'.
Segmentation fault (core dumped)

Somewhere I read that this should fix it:
- Make ModuleInfos immutable, which is something we should do anyhow.

But what are "ModuleInfos" ? Where I can find them and what exactly to do with them?

Which compiler/version?

It's a bug in 2.064-2 when using shared library. You as end user can't do much about it - wait for the next release where it should be fixed or use static linking for the moment.

This is part of core developers discussion and isn't something easily tweaked (else it would've been already fixed).

Thanks! Could be downgrading to 2.063 the solution?

If 2.063 works for you, sure it can.
