Summary: complex functions segfault

Initial Comment:
Hi,

many complex functions like exp, sin, sqrt crash on running:

#include <complex>
int main( int argc, char * argv[] )
{
	std::complex< double > z( 0, 2 ) ;
	std::exp( z ) ;
	return 0 ;
}

Using built-in specs.

Dear Earnie,

I think I'm reporting on the latest revision.

By the way, what is 'priority' reflecting on - severity or mood?
Or am I just too stupid to estimate?

Best regards.

Have you updated your mingw runtime and w32api libraries?

Since you modified the Priority setting I've reduced it to my lowest.
