That's a problem triggered by gcc 8 for Mingw-w64 with compiler options
-fstack-protector-all and -fstack-protector-strong. With any of those
options this simple test program also fails with SIGSEGV:
#include <windows.h>
int main(void) {
SYSTEM_INFO system_info;
GetSystemInfo(&system_info);
return system_info.dwPageSize;
}
With configure option --disable-stack-protector, the resulting binary
should work.
