Description John Maddock 2014-02-26 19:27:57 UTC
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.
Comment 2 Hannes Domani 2014-02-27 11:25:54 UTC
This seems to be a bug in mingw-w64.

Comment 3 Francois-Xavier Coudert 2014-10-08 14:59:34 UTC
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.
