do you really use/need the openGL-wrapper classes ?
if you don't use them (e.g. no [GEMglIndexi] in your patch), you most
likely have discovered a serious memory-leak.
if you don't need them (e.g. no [GEMglIndexi] in your patch), you should
compile Gem with "--disable-openGL" (well, it won't help you though)

which changes were required to get the textures working again.
could it be, you introduced a memory leak ?

most of my problems went away when using 0.7676 (found in
Debian/experimental).

does it help when you remove [pix_texture] (i know that it will look dull)
