Description of Problem: Compiler gets an ICE with the attached source Version-Release number of selected component (if applicable): gcc-3.1-0.18 How Reproducible: Compile the attached source file with given flags Steps to Reproduce: 1. gunzip ssa-botch-1.i.gz 2. gcc -c -O3 -fomit-frame-pointer -fno-exceptions -fno-rtti -pipe -s -mcpu=i686 -march=i686 -ffast-math -fexpensive-optimizations -mmmx -msse -fssa -fssa-ccp ssa-botch-1.i 3. Watch the abort happen Actual Results: [~]2 gcc -c -O3 -fomit-frame-pointer -fno-exceptions -fno-rtti -pipe -s -mcpu=i686 -march=i686 -ffast-math -fexpensive-optimizations -mmmx -msse -fssa -fssa-ccp ssa-botch-1.i /home/valdis/src/xemacs-21.5/lib-src/gnuslib.c: In function `connect_to_internet_server': /home/valdis/src/xemacs-21.5/lib-src/gnuslib.c:301: Internal compiler error in ix86_match_ccmode, at config/i386/i386.c:6919 Please submit a full bug report, with preprocessed source if appropriate.
