The offending line contains this piece of code:
gomp_fatal ("present clause: !acc_is_present (%p, "
"%zd (0x%zx))", (void *) k->host_start,
size, size);
This piece of code was introduced in r219682 which was applied on January 15
2015.
This issue was also discussed at the mingw-w64 mailing list @
http://sourceforge.net/p/mingw-w64/mailman/mingw-w64-public/thread/54cd7703.8080...@users.sourceforge.net/
and also contains some possible solutions
