Summary: glxgears segfault with swrast
Product: Mesa
Version: git
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
AssignedTo: mesa-dev@lists.freedesktop.org
ReportedBy: rand...@mail.ru
Using mesa from git (commit 41b38bd21c1031e65799c888a97d8a0c14ea2aaa - "
translate: s/varient/variant/") i can see following backtrace (in gdb)
(gdb) bt full
#0 0xb7980f17 in loopback_VertexAttribs2fvNV (index=2, n=138117492,
v=0x83b8154) at main/api_loopback.c:1204

Bug also present with nouveau_vieux_dri.so DRI driver (but mplayer -vo gl
works, so GL is not busted completely)
Mesa up to c6e33ca285f9eba26cae2fdd74fb5cc694f1e74b ("Disable direct rendering
on Cygwin") was fine.
My be this bug actually due to old gcc (gcc (Ubuntu 4.4.3-4ubuntu5)
4.4.3)/binutils GNU assembler (GNU Binutils for Ubuntu) 2.20.1-system.20100303
Or i just compiled mesa wrongly (i'll attach config.log in next message)
