Crash log with buffer overflow, backtrace, and memory map

I experienced a buffer overflow and crash while using xf86-video-intel built
from the current git head (0ca25c7) with --enable-debug. I've attached the
crash log.

This occurred while running chrome beta 36.0.1985.67. I'm unable to
consistently trigger the crash, but it's been occurring frequently, usually
when launching chrome or watching a flash video. I've tried downgrading to both
2.99.912 and 2.99.911, but I'm still experiencing crashes from overflows or
segfaults.

Please let me know if I can provide additional information about my setup.
Thanks for your help.
