            Bug ID: 80358
           Summary: [7 Regression] ICE (cc1 killed) building glib with -O3
                    on powerpc64le-linux-gnu
           Product: gcc
           Version: 7.0.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: doko at gcc dot gnu.org
  Target Milestone: ---

Created attachment 41152
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=41152&action=edit
preprocessed source

seen with trunk 20170407 on powerpc64le-linux-gnu while building glib with -O3.
With -O2 the build succeeds almost immediately, with -O3 it eats up all
available memory.

$ gcc -c -g -O3 gkeyfilesettingsbackend.i
