Thx for tracking this down.

that affects all classes derived from it. During the output of  a ptime, a
basic_stringstream object is created/destroyed and that is causing the memory
leak. I personally think Microsoft should release a patch for this but it
looks like they won't until the next release. You might be able to obtain a
hotfix by contacting Microsoft Technical support.

Perhaps it would work, but I have to say I feel highly unmotivated to spend my
time working trying to work around this vendor bug.  This bug is bad enough
that anyone seriously using C++ will have to use the workaround patch
available on the MS website.
