------- Comment #8 from janis at gcc dot gnu dot org  2008-08-12 23:57 -------
With r139042 the GCC Manual says that -fipa-pta is an experimental option that
does not affect code generation.

With so many dups, IMHO this ought to be fixed for the releases...

The problems with -O -fipa-pta seem to be fixed since GCC 4.4.0.
I checked all duplicates from comment #4 - #7.
