Backtrace

As mentioned in bug 28860, I'm getting a segfault in the game Yo Frankie if
shaders are enabled:

Program received signal SIGSEGV, Segmentation fault.
0xb6fc2bfc in translate_dst (t=<value optimized out>, 
    inst=<value optimized out>) at state_tracker/st_mesa_to_tgsi.c:193
193          return t->outputs[t->outputMapping[index]];

Bisecting leads to this commit:

I have just tried it here and it didn't crash. Could you please re-test the
game on your machine?

It's still crashing on the same line.

But I just noticed that I get the same crash in softpipe and llvmpipe, so I
guess this bug should be reassigned to Mesa core?
