Please provide enough sources to create an _executable_ that shows the failure.
We are dealing with runtime failure here.
A _short_ testcase (<30 lines) is nice to have, so all non-related parts should
be removed. Wandering through a maze of jumps certainly doesn't help to find
the problem.
An abort() should be called for wrong result, but at least wrong result and
expected result should be described to help trace the issue down.
BTW: Assembler dumps are not _that_ informative, especially without
-fverbose-asm ;)
