Mesa (R300 ?) segfault

[Vladimir D. <vo...@mi...>]

Hi all,

    I am getting the following segfault with recent checkout of Mesa (as of 
few seconds ago) and R300 driver:

-----------------------------------------------------------------------
Program received signal SIGSEGV, Segmentation fault.

-----------------------------------------------------------------------

This appears to be internal to the Mesa and I have run out of obvious 
things to check. For some reason the variables v and index get their 
values screwed up repeatedly and, furthermore, attrib_1_4 gets too far 
with unmodified index (still at too high value).

Any suggestions ?

This is with gcc 3.3.6

                        thank you !
