FReeBSD5.5 pthread_testcancel in 0.9.0-svn Grishenko

[Humperdinck]

Dear Forum,

I have a coredump that is reproducable on FreeBSD 5.5 STABLE with 0.9.0-svn Grishenko. All ports updated. Looks to be a pthread issue?

Vlc links to following:

tinca# ldd /usr/local/bin/vlc
/usr/local/bin/vlc:
libiconv.so.3 => /usr/local/lib/libiconv.so.3 (0x28077000)
libvlc.so.0 => /usr/local/lib/libvlc.so.0 (0x28164000)
libhal.so.1 => /usr/local/lib/libhal.so.1 (0x28230000)
libintl.so.6 => /usr/local/lib/libintl.so.6 (0x28238000)
libdbus-1.so.3 => /usr/local/lib/libdbus-1.so.3 (0x28241000)
libm.so.3 => /lib/libm.so.3 (0x28278000)
libpthread.so.1 => /usr/lib/libpthread.so.1 (0x28293000)
libc.so.5 => /lib/libc.so.5 (0x282b7000)
libstdc++.so.4 => /usr/lib/libstdc++.so.4 (0x28392000)

playing a playlist with the following command:

vlc playlist.m3u --sout "#transcode{acodec=mpga,ab=192}:std{access=udp,mux=ts,dst=239.255.255.255}"

where the playlist looks like:

filenamea.ogm
filenameb.ogm
...
filenamez.ogm

Gives a vlc.core after playing a few filenames. The gdb backtrack (and the gdb init) looks like this:

I wonder if a remap in /etc/libmap.conf would work and if so, to what other library?

[Humperdinck]

Dear Forum,

No, alas, changing the libmap.conf had no effect. Running vlc in gdb gives the following error and backtrace:

Program received signal SIGSEGV, Segmentation fault.

I'd be grateful for any input on this. Thanks In Advance.

Mapping vlc to another library has no effect. The core dump appears in exactly the same way. I used the below library:

[vlc]
libpthread.so.1 libthr.so.1
libpthread.so libthr.so

ldd /usr/local/bin/vlc
/usr/local/bin/vlc:
libiconv.so.3 => /usr/local/lib/libiconv.so.3 (0x28080000)
libvlc.so.0 => /usr/local/lib/libvlc.so.0 (0x2816d000)
libhal.so.1 => /usr/local/lib/libhal.so.1 (0x28239000)
libintl.so.6 => /usr/local/lib/libintl.so.6 (0x28241000)
libdbus-1.so.3 => /usr/local/lib/libdbus-1.so.3 (0x2824a000)
libm.so.3 => /lib/libm.so.3 (0x28281000)
libpthread.so.1 => /usr/lib/libthr.so.1 (0x2829c000)
libc.so.5 => /lib/libc.so.5 (0x282ad000)
libstdc++.so.4 => /usr/lib/libstdc++.so.4 (0x28388000)

So it's not a libpthread issue?
