thanks.

[GEM-dev] [pd-gem:bugs] Re: #211 VLC plugin crash Pd
thanks. my initial thought that the version of Gem you are running does not match the version of Gem the videoVLC plugin was compiled with (though it should detect that), seems to be highly unlikely given that setup. anyhow, valgrind is *not* a replacement for gdb, they are complementing each other. so i'd still like to have a gdb backtrace. the trick (as outlined in the original post) is, that gdb is interactive. after starting it, you have to manually run the program (with the `run` command) and after it crashed, you have to manually ask it for a backtrace (with the `bt` command) once you are done, you can exit it with the `quit` command. e.g. check the [debian help](http://wiki.debian.org/HowToGetABacktrace) for more information. and i forgot: please add the flags `-stderr -verbose -verbose` when running Pd (in addition to `-rt`), it might reveal something that gets lost otherwise. --- ** [bugs:#211] VLC plugin crash Pd** **Status:** open **Created:** Thu Jun 06, 2013 05:02 PM UTC by jack **Last Updated:** Thu Jun 06, 2013 05:08 PM UTC **Owner:** nobody Hello, Using VLC plugin crash Pd.
