Windows DEP problem with nested functions

[Nicholas Sherlock <n.sherlock@gmail.com>]

Hi all,

I'm using GCC 3.4.4 on Cygwin on Windows XP. The following program:

#include <pthread.h>

int main() {
        pthread_t thread;

    void * task(void * arg) {
      return NULL;
        }

        pthread_create(&thread, NULL, task, NULL);
        pthread_join(thread, NULL);

    return 0;
}

only runs if DEP (Prevention of code execution on data pages) is turned 
off in Windows settings. I get a segfault if DEP is turned on. Is this a 
GCC problem, or a Cygwin problem?

Cheers,
