--- Comment #2 from howarth at bromo dot med.uc.edu --- I am not seeing identical g++.log's being created here from dejagnu 1.5.1 and 1.5.2 on x86_64-apple-darwin14 with separate runs of... make -k check RUNTESTFLAGS="--target_board=unix'{-m32,-m64}'" on the same build of gcc trunk. Furthermore, running contrib/test_summary under dejagnu 1.5.1 against the g++.log created under dejagnu 1.5.2 doesn't eliminate the bad summary results reported.
