I cannot help you to solve this subtitles problem (sam is the SPU expert :-) 
but I just wanted to report that I also have problems running vlc under 
GDB-5.0.
The problem is related to the sdl library (bug ?), and just compiling VLC 
without sdl support (./configure --without-sdl --enable-debug) solves the 
problem.
