            Bug ID: 79198
           Summary: [7 Regression] r244802 causes out of memory during PGO
                    bootstrap
           Product: gcc
           Version: 7.0.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: trippels at gcc dot gnu.org
                CC: jamborm at gcc dot gnu.org
  Target Milestone: ---

Since r244802 I run out of memory when compiling bitmap.c
during stagefeedback (PGO bootstrap).

ipa_node_params_t::duplicate keeps allocating memory until the OOM killer kicks
in.
