Some SDL programs crash(ed) when using :
* SDL_Init(SDL_INIT_CDROM or SDL_INIT_EVERYTHING)
* supermount (in /etc/mtab or /etc/fstab)
* alloca

Two examples were reported on mandriva bugzilla : holotz-castle and avidemux.

For instance :
$ holotz-castle
*** glibc detected *** holotz-castle: double free or corruption (out):
---8<------

A workaround was first found :
$ SDL_CDROM=/dev/cdrom holotz-castle

Then i proposed this fix, which seem to be OK for other cooker users :
