--- Comment #5 from Julien Margetts <jmargetts at ocz dot com> --- Yes, I applied both patches, and the test failure is still present, but on closer inspection, it is no longer a segfault, but an internal compiler error: The new assertion in the patch is firing: gcc_assert (REG_P (operands[0])); The discussion in PR62254 suggests not all cases are covered (hence the new asserts I guess) so I think this is just another as yet unreached corner case I guess either this bug, or 62254 should be re-opened?
