            Bug ID: 60349
           Summary: Any call to expq (or libquadmath function that might
                    possibly call expq) segfaults in mingw-gcc.
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P3
         Component: libquadmath
          Assignee: unassigned at gcc dot gnu.org
          Reporter: john at johnmaddock dot co.uk

This effects gcc-4.8.1 and 4.8.2 (at least), on both mingw32 and mingw64, the
following program segfaults:


#include <quadmath.h>

int main()
{
   __float128 a = expq(2.0Q);
    return 0;
}

Mingw gcc-4.7.x and Linux are obviously both fine.

Please provide at least a backtrace with debugging symbols available.

This seems to be a bug in mingw-w64.

This was apparently a bug in mingw itself, and was fixed a while back. I'm
closing this report.

Please reopen it, with added info (such as backtrace), if you still see this
problem with latest mingw.
