Description Moshe Gor 2006-05-15 22:57:16 UTC 
src/mesa/drivers/dri/tdfx/tdfx_tex.c uses
mesa_malloc().
src/mesa/main/teximage.c uses
_mesa_align_free().

Segmentation fault, system hangs, etc.

Proposed solution:
src/mesa/drivers/dri/tdfx/tdfx_tex.c:
replace _mesa_malloc() by _mesa_align_malloc()
in three allocations:
texImage->Data = _mesa_malloc(....)

See src/mesa/main/teximage.c:
Mesa uses _mesa_free_texmemory(texImage->Data),
which calls _mesa_free_texmemory(....),
which in turn uses _mesa_align_free(....).
Comment 1 Brian Paul 2006-05-19 03:08:12 UTC 
This has been fixed in Mesa 6.5 by calling _mesa_alloc_texmemory().
Closing this bug.
