            Bug ID: 61759
           Summary: internal compiler error: in objc_eh_runtime_type, at
                    objc/objc-next-runtime-abi-01.c:2792
           Product: gcc
           Version: 4.8.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: objc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dougmencken at gmail dot com

I cannot compile some LibreOffice .mm files using gcc-4.8.3 on OS X 10.5. Many
of them fails with ICE when -O2 is used, but with -O(1) they compiles.

I cannot also compile .cxx files when -x objective-c++ is used on gcc line.

All of them ICE at the same spot: "in objc_eh_runtime_type, at
objc/objc-next-runtime-abi-01.c:2792"

This one (vcl/osx/a11yselectionwrapper.mm) ICEs even with -O:
