Thank you for this report.

The proper way to proceed on these kinds of bugs is to minimize the test 
case, so you end up with the smallest possible run of code that 
demonstrates the bug.

The general process for runtime failures is to 1) try to all get all 
relevant code into a single .c file that still demonstrates the problem, 
2) preprocess it with -E or -save-temps 3) remove all code you can while 
retaining the bug and not causing other failures.
