As I can see you using not my builds, but cross-compiler.
Moreover, this error is reproduced using the native compiler(gcc-4.8.2-x86_64-w64-mingw32-posix-sjlj).
Because the error occurs when linking, I assume that the libfec.a is the reason for the error.

I have no other ideas...

[João M. S. Silva]

You can close this. The libfec.a I was using was a Linux library, sorry. Also from IRC discussion this is a bug in ld.
