--- Comment #3 from Markus Eisenmann <meisenmann....@fh-salzburg.ac.at> --- Further information on (IMHO) problematic optimization / tests: Option -Og does not cause this segfault (as already written), but the option -Og and -ftree-bit-ccp will show the ICE; using the option -ftree-bit-ccp (alone) will not.
