The problem is with linking, forcing won't make a difference. I can replicate the problem on Win7 64bit with Strawberry 5.16.2, MinGW 4.6.3. Some quick google fu suggests a MinGW 4.6 problem. A starting point for your investigations.

Update: Follow this.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
