Gdb output of "shader_time" crash when not using "--enable-debug" asserts

(disregard previous comment, I did incomplete build)

>From the Gdb output one can see that without "--enable-debug" asserts, Mesa
with "shader_time" does past-the-array-end access, tries to access data through
invalid pointer it got that way, and crashes.

Valgrind doesn't work with Witcher2, so I couldn't get info on whether
something goes wrong already earlier.
