Sorry, for the confusion.  I tried to demonstrate how $r17 was loaded
from memory starting from $r11.  You can see the load earlier in the
disassembly.  The values in $r22 and $r17 were consistent with the fault
address.  The value loaded from memory into $r17 was also consistent
with what was recorded in memory in the core dump.  It appeared to me
that only a single word was corrupted.

Unfortunately, gdb dropped core on the core file, so there's nothing
more that can be looked at.  This was caused by a malloc double free
error.
