You can test your code with *smaller* testcases to see how GCC behaves,
and which pass may be the culprit (even if there is no problem in GCC per
se, you can still use this info to test with that pass disabled, etc.)

Use -ftime-report to get a detailed report on where time (and GC memory)
is spent.
