Bug #: 48779
Summary: padsp makes VLC media player (actually freopen())
crash
Classification: Unclassified
Product: PulseAudio
Version: unspecified
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: tools
AssignedTo: [email protected]
ReportedBy: [email protected]
QAContact: [email protected]
CC: [email protected]
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;
}
---->8-------->8-------->8-------->8-------->8-------->8----
I suspect the root cause is similar to this (Firefox bug):
