This error occurs with head using GCC 4.8 on linux.

This is identical to the thunk issue we had a while ago.  It broke with this change.

https://github.com/D-Programming-GDC/GDC/commit/cd8bb6d03ae3134a4976689eab312e2bb57701fc#gcc/d/d-objfile.cc

weakref allowed the Thunk symbol to be associated with the actual symbol. Switching to WEAK provides no such association.

Additionally, the weakref solution doesn't work for MinGW resulting in rather interesting crashes.  Mostly an issue with binutils and some obscure interaction I couldn't trace.

The solution is the same as before and a pull request has been made. https://github.com/D-Programming-GDC/GDC/pull/42

Does the weakref solution still produce phantom crashes in binutils for MinGW?

Looks good.  Couldn't reproduce the weakref crashes and some more complicated testcases passed.
