Summary: Mplayer/alsa-lib dl_close segv.
Product: glibc
Version: 2.14
Status: NEW
Severity: normal
Priority: P2
Component: libc
AssignedTo: drepper.fsp@gmail.com
ReportedBy: smf.linux@ntlworld.com
With glibc 2.14 I am getting the following issue reported by valgrind, mplayer
is subsequently reporting a segv. Tested on Quad Core Phenom and IBM thinkpad
LFS development systems.
Kernel is 3.0, GCC is 4.6.1 and binutils 2.21.1.
Under valgrind mplayer reports:

MPlayer interrupted by signal 11 in module: ao2_init
- MPlayer crashed by bad usage of CPU/FPU/RAM.
Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
gcc version. If you think it's MPlayer's fault, please read
DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
won't help unless you provide this information when reporting a possible bug.

A crash in glibc does not mean that glibc is buggy, it could also be a bug in
the usage. We need more information and a stand alone test case.
