Here is the entire stack trace for the math library error I get:

Sigh... those are still truncated and don't give the full template parameters :-(

I admit to being a bit perplexed by this, particularly as the IBM AIX tests are mostly passing with xlC 10.1, options used are here: http://beta.boost.org/development/tests/trunk/developer/output/ IBM_Canada_Ltd-boost-bin-v2-libs-config-test-config_info-test- vacpp-debug.html

Hi John, I knew it compiled with xlC 10. And clearly IBM has improved their compiler significantly since I bought xlC 6. I figure xlC 6 is like MSVC 6 - it does templates but not really. It makes sense - xlC 6 is four versions behind and so is MSVC 6. It's just too old. Sorry about the truncated error messages - I have no idea how to make them contain more detail. Jerry
