see comment 5
Comment 7 wbrana 2012-09-24 11:48:51 UTC 
still broken
Comment 8 Jakub Jelinek 2012-11-19 14:36:53 UTC 
Can you still reproduce it?  Are you using stock trunk, not some extra patches on top of it?  If you rebuild the source file which failed checksum checking with the options passed to g++ normally to compile it plus -fcompare-debug, does it fail with an -fcompare-debug failure?  If yes, please attach the preprocessed source of it and all command line options.
