Can you provide the .i file so that I can duplicate your issue?

Use the -EP -P options to create the .i file like:
$ icpc -c ....... -EP -P test.cpp
$ icpc -c ....... -EP -P test.cpp

John,
I tried to reproduce your error with the .i file and the small piece of code you provided. I couldn't reproduce the error. So it might be related to your environment. Could you please give me the following additional informations:
- Linux distribution?
- 32/64 Bit?
- Command Line you used to get the error on the small reproducer
- GCC Version (4.6?)
Thanks,
Alex

John,
you are using a very uncommoncombination of GCC and OS. Gentoo is not a supported distribution and therefore its not tested. Using a Release Candidate GCC is also not a supported option.
If you have another computer with a supported Linux distribution this would be the easiest way for you to proceed. At the moment the following Linux distributions are supported:
- Asianux* 3.0, 4.0 (Deprecated)
- Fedora* 15
- Red Hat Enterprise Linux* 4 (Deprecated), 5, 6
- SUSE LINUX Enterprise Server* 10, 11 SP1
- Ubuntu* 10.04 LTS, 11.04
- Debian* 6.0
I can confirm that your reproducer dont show any error on RHEL6.
If you want to continue investigation on Gentoo, you might try to use a GCC 4.5.
Thanks,
Alex

I was able to reproduce the issue on SUSE Linux Enterprise Server 10.

Thanks ElroyI can reproduce it as well on a SLES 10 system.
A quick workaround is to compile with lower optimization(-O1 worked for me) or omit the -fPIC option.

John,
to workaround the issue, you can also use a pragma to disable optimization only for certain functions or parts of the code. This should help to reduce the performance impact.
The interesting pragmas are:
Hope this helps you. I will forward the issue to our engineering.
Thanks for reporting and your help on isolating the issue.
Alex
