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
Created attachment 30386
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30386&action=edit
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.
