            Bug ID: 64552
           Summary: Build broken for cris-elf and others
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hp at gcc dot gnu.org
                CC: marxin at gcc dot gnu.org

Observe crash with ./cc1  -quiet -fpreprocessed unwind-dw2.i -O2 -o
unwind-dw2.s

With a commit in the range (219373:219378] but from the crash message obviously
r219377, the build is broken for cris-elf, and
<http://gcc.gnu.org/ml/gcc-patches/2015-01/msg00534.html> indicates a similar
(but not identical) crash for arm-eabi.  Configure for cris-elf, then build and
observe, building libgcc:
