problem using ldc 1.0.0 as D compiler

[Antonio Corbi via Digitalmars-d]

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.
