Core dump on 32-bit Cygwin if program calls dlopen

[Ken Brown]

I'm getting a core dump on exit from a program that does nothing but 
call dlopen.  (But the call to dlopen succeeds.)  This happens only in 
the 32-bit case.  Here's a simple test case.

$ cat test_dlopen.c
#include <stdio.h>
#include <dlfcn.h>
int
main()
{
  const char *dllname = "cyggs-9.dll";
  void *handle;
  printf ("Trying to dlopen %s...", dllname);
  handle = dlopen (dllname, RTLD_LAZY);
  if (handle)
    {
      printf ("succeeded.\n");
      return 0;
    }
  else
    {
      printf ("failed.\n");
      return 1;
    }
}
$ gcc test_dlopen.c

$ ./a
Trying to dlopen cyggs-9.dll...succeeded.
Aborted (core dumped)

$ echo $?
134
