Core dumped when executed

Description of problem:
A crash occurs within the _d_toObject function of the D runtime when calling GC.collect(), when compiling with the ldc2 compiler (the same does not occur when using the dmd compiler from DigitalMars)

Version-Release number of selected component (if applicable):
ldc2 (0.12.0 -- based on DMD v2.063.1 and LLVM 3.3) (x86_64)

How reproducible:
The following code triggers the crash:

  import core.memory;
  void main() {
    GC.collect();
  }

Steps to Reproduce:
1. $ ldc2 gcbug.d
2. $ ./gcbug

Actual results:
Violación de segmento (`core' generado)

Expected results:
No crash =)

Additional info:
The crash does occur (according to gdb) inside the _d_toObject function (core attached)
