Crashes with Windows (mingw/msys)

After failing with cygwin, I tried mingw. After a few trivial fixes ( https://github.com/mifritscher/goldy/tree/mingw-bringup ), it compiles - but crashes right after start:

Ah short gdb session reveals:

Btw, I get following warnings:

But I think these are not critical.
