Hi,

I have a working gcc HEAD build from about 2 weeks ago.  If you send me some
standalone test code, I would be happy to test it.

I also have 2.95.3 too and will test with both.

Just create a main with a call to printtrace and have printtrace print all
the values and just return and I will test it for you.

Take care,

Kevin
