I'm not sure if it's important, but the crash isn't reproducible  if
--enable-debug is used. This is from a run with optimisations turned off
through CFLAGS (values are optimised out otherwise).

(gdb) print index
$1 = 2
(gdb) print t->outputMapping[index]
$2 = 2228224
(gdb) print t->outputs
$3 = {{File = 0, WriteMask = 0, Indirect = 0, Saturate = 0, Predicate = 0, 
    PredNegate = 0, PredSwizzleX = 0, PredSwizzleY = 0, PredSwizzleZ = 0, 
    PredSwizzleW = 0, Index = 0, IndirectIndex = 0, 
    IndirectSwizzle = 0} <repeats 32 times>}
