When I compile my code, if I compile it -O2, it compiles and runs fine. if I
compile the code without it, my program segfaults while rendering text with
FTGL. I've made no changes to anything in between compiles. Same FTGL code
works fine in win32 (vs2010).

system: ubuntu 11.04 & 10.04
gcc version: 4.5.2 (from deb package)
command line: gcc -I /usr/include/freetype2 -o ~/BlocksWorld/BlocksWorld
Src/*.cpp Src/Linux/*.cpp Src/GUI/*.cpp -lpng -lGL -lGLU -lftgl
