I looked at the new and delete runtime calls when I first noticed them. They originate from STL usage in the FB database creation code, in the FB library. IMO, this is correct. An STL implementation that makes calls to "the" global new or delete operators *should* call the replacement operators defined in the program object file. That's what is happening. Since your hack relates to certain FB defined classes, not STL classes, I don't think there is a problem with these calls.

Rather than post the verbose backtraces, I'm e-mailing you the source for the modified test program, as you requested, so you can resolve any questions you may have.

If you don't mind confusing, proprietary, non-portable code. We'll just have to "agree to disagree" on this point. ;-)

Sounds good!
