Core dump on 32-bit Cygwin if program calls dlopen

Trying to help ...

----- test program
#include <windows.h>
#include <stdio.h>

//int main (int argc, char **argv)
int main (int argc, char *argv[])
  HMODULE m = LoadLibrary (argv[1]);
  if (!m)
    printf ("%s: %lu\n", argv[1], GetLastError ());
    printf ("Success.\n");
    // 15/07/2014: currently resulting in a crash on 32-bits only (gcc only)
  return 0;

The test program above fails (abort) for every cyg*.dll in /usr/bin that pulls in cyggcc_s-1.dll.

(if not, the test program exits normally)

(using the same compiler and cygwin1.dll as Ken did)
