Summary: Darwinia crashes in rv670 when starting a level
Product: Mesa
Version: git
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/R600
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: fran...@gmail.com
Darwinia starts and the world selection works ok, but when entering a level it
segfaults with the following backtrace:
#0 0xf7c58dc6 in memcpy () from /lib32/libc.so.6

It seems the problem is the call to _mesa_texstore_rgba8888 with dstAddr=0x0.
I had to apply the patch in here: http://pastebin.com/m5e85e97f to avoid the
following assertion:
radeon_mipmap_tree.c:117: compute_tex_image_offset: Assertion `lvl->size > 0'
failed
I don't know if the bug is caused by that.
This is with the latest mesa git (commit
6a09c9d2d891a7118bc7c07d03900d69154116ba, 2009-09-22 11:35:56 GMT).
