g++ 4.8.2, shipped with Ubuntu 14.04, generates incorrect code for checking
the loop termination condition, resulting in never ending loops in
HashMapTest().
Disable the optimizations for this function for 4.8.[012] as the bug seems to
be fixed in 4.8.4 and several similar (but not really identical) bug reports
in gcc bugzilla have been fixed in 4.8.3.
This should allow the unit tests on Linux buildbots, using 4.8.2, to run to
completion again.
This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.
Closes#14487.
