Comment 2 for bug 1071593

Start VLC under padsp on Linux:
# padsp vlc -Idummy vlc://quit
VLC media player 2.0.1 Twoflower (revision 2.0.1-0-gf432547)
Segmentation fault

The same process runs and exits fine without padsp. In fact, even this trivial and obviously correct piece of C code crashes with padsp while calling glibc freopen():
----8<--------8<--------8<--------8<--------8<--------8<----
#include <stdio.h>
#include <stdlib.h>

int main(void)
{
        FILE *stream;

        stream = fopen("/dev/null", "w+t");
        if (stream == NULL)
                abort();
        stream = freopen("/dev/null", "w+t", stream);
        if (stream == NULL)
                abort();
        fclose(stream);
        return 0;
}

I suspect the root cause is similar to this (Firefox bug): https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/810214/comments/8
