Hi kib, -current, seems we have a segfault in rtld when updating the multimedia/vlc port from the version currently in ports to the 2.0.3 CFT version from here: http://people.freebsd.org/~nox/tmp/vlc-2.0.3-006.patch (If you test the LIVEMEDIA knob you also need this update: http://people.freebsd.org/~nox/tmp/livemedia-20120404-001.patch ) In article <20120804110952.4f3a9cfd_at_ernst.jennejohn.org> you write: >On Fri, 3 Aug 2012 18:36:33 +0200 >Juergen Lock <nox_at_jelal.kn-bremen.de> wrote: > >> On Fri, Aug 03, 2012 at 05:00:37PM +0200, Rainer Hurling wrote: >> > On 03.08.2012 14:27 (UTC+2), Gary Jennejohn wrote: >> > > On Thu, 2 Aug 2012 22:56:26 +0200 >> > > Juergen Lock <nox_at_jelal.kn-bremen.de> wrote: >> > > >> > > [trimmed irrelevant content] >> > >> Ok I added that check: >> > >> >> > >> http://people.freebsd.org/~nox/tmp/vlc-2.0.3-005.patch >> > >> >> > >> Enjoy, :) >> > >> >> > > >> > > AMD64 on HEAD. >> > > >> > > I always get this error, no matter which patch I use: >> > > >> > > GEN ../modules/plugins.dat >> > > gmake[2]: *** [../modules/plugins.dat] Segmentation fault: 11 (core dumped) >> > > gmake[2]: Leaving directory `/usr/ports/multimedia/vlc/work/vlc-2.0.3/bin' >> > > gmake[1]: *** [all-recursive] Error 1 >> > > gmake[1]: Leaving directory `/usr/ports/multimedia/vlc/work/vlc-2.0.3' >> > > gmake: *** [all] Error 2 >> > > *** [do-build] Error code 1 >> > >> > I get exactly the same error with CURRENT amd64. >> > >> Hm how old are both your installed src and ports?

I Cc'd -current and kib (who did the majority of the recent rtld commits), maybe he has an idea. Seems dlopen() was called from here, /usr/ports/multimedia/vlc/work/vlc-2.0.3/src/posix/plugin.c , line 62: /** * Load a dynamically linked library using a system dependent method. * * \param p_this vlc object * \param psz_file library file * \param p_handle the module handle returned * \return 0 on success as well as the module handle. */ int module_Load( vlc_object_t *p_this, const char *psz_file, module_handle_t *p_handle, bool lazy ) { #if defined (RTLD_NOW) const int flags = lazy ? RTLD_LAZY : RTLD_NOW; #elif defined (DL_LAZY) const int flags = DL_LAZY; #else const int flags = 0; #endif char *path = ToLocale( psz_file ); module_handle_t handle = dlopen( path, flags ); if( handle == NULL ) { msg_Warn( p_this, "cannot load module `%s' (%s)", path, dlerror() ); LocaleFree( path ); return -1; } LocaleFree( path ); *p_handle = handle; return 0; } Thanx, :) JuergenReceived on Sun Aug 05 2012 - 13:33:51 UTC
