Description Philip Langdale 2004-09-10 18:54:18 UTC 
Compile and run the attached test case under memprof and observe that binding to
a named slot appears to cause a leak (or two).

Then recompile with I_WANT_TO_LEAK undefined and observe that creating and
binding the slot all inline does not cause the leak

Memprof leak log

This is the log of running memprof against the test case.
Comment 3 Martin Schulze 2004-10-02 18:32:13 UTC 
Thanks for pointing this out.
The problem was that the functor stored in struct typed_slot_rep never got
destroyed because there is no virtual dtor.
I've fixed this in cvs.
