Hi,

Here's the simple demo:

/***************************
#include <quadmath.h>

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

***************************/

With recent MinGW64 ports of gcc, that program builds ok, but running it 
results in a crash.
Seems to happen with 4.6.3, 4.7.0 and 4.8.1 (both 32-bit and 64-bit 
versions); I haven't tried any other versions.

No such problem with mingw.org's gcc-4.7.0, nor with gcc-4.6.3 on Ubuntu.

Cheers,
Rob
