Comment 29 for bug 1608180

Thanks for the back trace. Can you also issue the following commands (in gdb, after it crashes, assuming the crash address from the backtrace did not change):

(gdb) x/i 0x000000080159472b
(gdb) disass 0x000000080159472b

or

(gdb) layout asm

This may help to locate the critical place.
