--- Comment #16 from Michael Karcher <gcc-bugzilla at mkarcher dot dialup.fu-berlin.de> --- The bug seems to be quite similar to the infamous "sloth that was dropped on the head as a baby"-bug Linus discovered (https://lkml.org/lkml/2014/7/24/584 , https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61904). -fcompare-debug passes if -fno-var-tracking-assignments is passed as compiler option.
