           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 at lists.freedesktop.org
        ReportedBy: randrik at 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)
