Amanjit -

Yes, I'm running 1.33.  I'll upgrade and post if it's still a problem.  But it sounds like it won't be!

Thanks,

TT

Hi Tom
> I always get the memory leak trace at the end of this post when I run a trivial application that uses boost threads (source below).
I can confirm that this happens with boost 1_33_1 and dissapears with
the current version from CVS (named 1_35 there, don't know anything
about 1_34 thought). I am running vc8 and/or vc7.1. with 1_33_1 the leak
looks like this:
