Bug #: 51739
Summary: g++ cpp compiler crash with -O3
Classification: Unclassified
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: tim6...@gmail.com

preprocessed source file to reproduce crash
g++ crashes when compiling the attached source file. This file was generated
with -E. The compiler also crashes when usign -save-temps on the original
source file. I've not encountered any other files that cause this problem. The
problem is consistantly reproducible (on my system).
I'm not responsible for nor do I condone this rat's nest code, but it does work
with older g++ versions (ex, 4.1, 4.4) and without -O3. Also, the options -Wall
-Wextra etc did not turn up any obvious problems.
The system is a newly installed Xubuntu 11.10 running in a fairly vanilla
VirtualBox setup (single processor, 64 bit on a 64 bit host machine).
Additional information is below. Apologies, I have not tried with the latest
version of g++.
