            Bug ID: 89084
           Summary: dungeon defenders crashes after
                    vbo_exec_DrawRangeElements call
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965

backtrace of the crash

There is a bugzilla entry for the game already:
https://bugzilla.icculus.org/show_bug.cgi?id=5847

I was curious if mesa could validate the input of the
vbo_exec_DrawRangeElements call to return an error instead of segfaulting later
on, even if this is an application bug.

If there is nothing mesa can do, because of integrity with OpenGL specs I am
fine with a CLOSED-INVALID, but it would be nice to have some optional
workarounds nethertheless.

mesa-e68b67b53fce39a8c93188262d9e795ca50750ac used for the backtrace.
