| Re: [cdt-dev] CDT+GDB crash when Debug programs include "complex number" |
I test on the linux platform, it works well. but on windowsXP(
eclipse3.1+CDT3.0+mingw3.1), gdb.exe crash, when display the comlex
numbers, target request fail....
if you dont let it display the comlex nubmer,it works well.
the attached is a gif file of the screen copy, to reproduce it.
the code is following:
==========================================
#include <math.h>
#include <complex>
using namespace std;
int
main (void)
{
complex < double >im = complex < double >(0.0, 1.0);
return 0;
}
==========================================
