            Bug ID: 57732
           Summary: [4.8 / 4.9 Regression] ICE (segfault in libisl)
                    building drizzle on 32bit targets (at least arm-linux
                    and i586-linux)
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: doko at gcc dot gnu.org

preprocessed source

g++ -c -g -O2 -std=gnu++98 -fPIE -floop-parallelize-all -fno-strict-aliasing 
cmpfunc.ii 

leaving out the -floop-parallelize-all avoids the ICE.
