Jan Hubicka said:
the problem is caused by tree profiling affecting const/pure function
autodetection resulting in CFG missmatch in between profiling and
feedback passs. As disucssed with Rth, all the alternatives of fixing
this I can think of seems nasty and bit invasiave for 4.0. [...]

This should be revisited for 4.1
