Bug ID: 60506
Summary: g++ reports "internal compiler error" using SSE2 and
not entirely beautiful programming
Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: blocker
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jenkinsj89 at yahoo dot ca
Host: i86_64-pc-cygwin
Target: i86_64-pc-cygwin -march=corei7
I compiled the enclosed program with:
g++ -S -v -Wall -Wextra -std=c++11 -march=corei7 -save-temps rabbit-gccbug.cc
and it reported the text hereafter pasted. It reports the same error
if "-O2" is enabled, and it also reports the same error if
"-fno-strict-aliasing -fwrapv -fno-aggressive-loop-optimizations"
is provided.
As requested, I am attaching the preprocessed output rather than the original
program, but please note that the only included file is <cstdint>.
