digitalmars.D - problem using ldc 1.0.0 as D compiler

Hi folks!

I'm using ldc version:
LDC - the LLVM D compiler (1.0.0):
   based on DMD v2.070.2 and LLVM 3.8.0
   built with DMD64 D Compiler v2.071.0
   Default target: x86_64-unknown-linux-gnu
   Host CPU: core2

And when trying to run this code (it compiles ok):

import std.regex;

void main(string[] args) {
   processLine ("abc int char[]");
}

long processLine (string l) {
   long count;
   int[string] lpb;

   lpb = ["char" : 0, "int" : 0, "for" : 0];

   foreach (rw; lpb.byKey) {
     string re = r"(^|\W)" ~ rw ~ r"(\W|$)";
     count = 0;

     auto r = matchAll(l, re);
     foreach(c; r) count++;

     lpb[rw] += count;
   }

   return count;
}

I get this error:
./ldcfail
Fatal Error while loading '/usr/lib/libphobos2-ldc.so.70':
         The module 'std.regex.internal.parser' is already defined 
in './ldcfail'.

The same code compiles and executes ok with both dmd (DMD64 D 
Compiler v2.071.0) and gdc (gdc (GCC) 6.1.1 20160501).

Is this a bug in ldc or is it somehow related to my code?
Thanks for your help.

This is a bug in LDC, or rather its interplay with certain system 
linker versions. This issue has also been reported at 
https://github.com/ldc-developers/ldc/issues/1534, but we are not 
sure how to reproduce it yet. Could you please add your test case 
and system details there? (Of particular interest are the version 
of the Linux distribution you are using, and `ld --version`.)

As a workaround, you can always use Phobos as a static library in 
the meantime (e.g. from our the binary release packages).

you could use ldc-git from aur,
https://aur.archlinux.org/packages/ldc-git/
this has static phobos

I'm linking phobos and druntime into another shared lib then I'm 
using it in projects.

A fix for this just landed in Git master: 
https://github.com/ldc-developers/ldc/commit/6de981af757b00a91b36ae94d9ce9a8a81cfabf9

It would be great if you could build LDC yourself to verify that 
the issue is gone – be sure to open another ticket if the issue 
persists!

Would you mind making a point release with it if fix is confirmed?

That's Kai's territory, but I'm sure he'll agree that this a 
sensible thing to do.
