Summary: SIGSEGV at brw_wm_populate_key during KDE login with
gallium sw renderer enabled
Product: Mesa
Version: 7.10
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
AssignedTo: mesa-dev at lists.freedesktop.org
ReportedBy: Hugo.Mildenberger at web.de
using mesa-7.10 with --enable-asm on Gentoo/hardened with Intel Mobile GM965:
# eselect mesa list
i915 (Intel 915, 945)
[1] classic
[2] gallium *
i965 (Intel 965, G/Q3x, G/Q4x)
[1] classic
[2] gallium *
r300 (Radeon R300-R500)
r600 (Radeon R600-R700, Evergreen, Northern Islands)
sw (Software renderer)
[1] classic
[2] gallium *
While all other configurations have been unusable due to screen corruption, the
above listed configuration crashed xorg-server-1.9.3.901, obviously while KDE
was trying to switch to OpenGL during login.
With tex being NULL, this line of brw_texture should be the point where mesa
finally triggers signal 11:
90 assert(tex->b.vtbl == &brw_texture_vtbl);
Since brw_texture doesn't that much except casting a pointer,
that line should probably read
assert(tex && tex->b.vtbl == &brw_texture_vtbl);
