Yhe problem is the default stack size on cygwin (2 MB), you can increase it. $ gcc -o aa -Wl,--stack,8388608 aa.c $ ./aa ok $ cat aa.c #define NXY 7000 int xy[NXY][NXY]; main(){ printf("ok\n"); } Gerrit -- =^..^= -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
