And sometimes it's cause crashes.

When i building it from sources with -O0 flag, builds faults with errors, and after bug reporting to gcc, they answers it's bug in sdl's asm-code. And when i changes ./include/SDL_config.h and comments "#define SDL_ASSEMBLY_ROUTINES 1"(after ./configure command) building error and bug has gone on any optimization level.

Additional info:
* package version(s)
sdl-1.2.14-7
smpeg-0.4.4-5

Steps to reproduce:
Run testapp from attachment on current sdl lib. And run it on compiled with commented "#define SDL_ASSEMBLY_ROUTINES 1"
