- Hi Gnu,
-
- There appears to be a deviation from expected c++ behavior with the
- new[] operator call. According to the Lippman C++ Primer calls to
- allocate an array of objects using "new some_class [n]" should go
- through the default allocator, and bypass any overloaded class member
- operator functions. The following code demonstrates that this does not
- occur with g++-2.3.3.

-
- I haven't looked at the compiler internals to see what is going on, it
- took me a long time to figure out what was going on in the program I
- was using!

- Hope this is of help
