Emil,

The platform is vc++ 8, boost 1.37.

Since submitting my inquiry to the list, I cut my boost.exception code out
into a separate test program that is very similar to the test code you gave
in your reply (thanks for that) , but my test program does not leak, so the
problem seems to involve some aspect of context from the original
surrounding code that I'm not yet able to identify.  I'll write back with an
update if I can isolate the interaction that triggers the leakage.
