           Summary: IPA reference tends to explode in memory use with
                    -fprofile-generate
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: hubi...@gcc.gnu.org


Compiling Mozilla, IPA reference OOMs for me after allocating about 9GB of
bitmaps.  It is because the counters inserted to every function by
profile-generate are especially bad for the datastructure used by
IPA-reference.

As a temporary workaround, I will probably disable IPA reference with profiling
is active.
