plaympeg crashes on exit
Last modified: 2008-05-01 11:38:01 EDT
I am trying to compile tuxtype (http://www.geekcomix.com/dm/tuxtype/) and it
runs ok, but crashes when exiting. (Locking my screen in a low-resolution
mode.) I have noted, though, that plaympeg crashes in the same way, so a bug
report versus smpeg seems a proper place to start, even if I suggest arts.
The crash appears to happen in the library libmcop from the arts
#0 __pthread_mutex_lock (mutex=0x15579080) at mutex.c:99
#1 0x15cf3a58 in __tcf_0 () from /usr/lib/libmcop.so.1
#2 0x1583d50b in exit (status=0) at exit.c:54
#3 0x15828630 in __libc_start_main (main=0x8057a60 <strcpy+58808>, argc=1,
ubp_av=0x3ffff344, init=0x8049060 <_init>, fini=0x8058300 <_fini>,
rtld_fini=0x15563cc4 <_dl_fini>, stack_end=0x3ffff33c)
Guessing this had something to do with threading, and noting there is a library
libmcop_mt which might mean "multi-thread-safe", I tried changing the links
libmcop.so and libmcop.so.1 to point to libmcop_mt.so.1.0.0 rather than the
default variant without _mt. That removes the crash, apparently fixing the
problem. But I don't know the proper way to solve this. libmcop doesn't appear
among the explicit dependencies shown by ldd; I suppose it is loaded via dlopen.
But the arts package is completely free from any documentation.
Version-Release number of selected component (if applicable):
It's fixed in smpeg-0.4.4-9. it works with new arts-1.0.0. You will find them in next
