Richard,

Can you confirm that this occurs only with -O2 ?

Can you revert the patch on a local tree and confirm this is it?

Would you be willing to help me debug this, the patch is not that complicated?

If not is there anyone with SPEC that I can work with?

Also, I do work out of my home and a Non-Disclosure Agreement is no problem to me.

Thanks,

Jerry
