Subject: Core dump on 32-bit Cygwin if program calls dlopen
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Content-Transfer-Encoding: 7bit

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
