             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: unassigned@gcc.gnu.org
        ReportedBy: tim6502@gmail.com


Created attachment 26228

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++.

Killed means you don't have enough memory and kernel OOM killer decided to kill
GCC.  This compiles just fine for me, but it needs roughly 1.2GB of memory to
compile it.
