Do you have a test case?  I tried to make one but "it didn't fail for
me".  If you can generate a test case I'm sure I could fix the problem.

Barring that can you try building a version of the dll with
TP_NUM_W_BUFS set to 11, 12, 13, etc.  to see if that fixes the problem?
It is barely possible that the number is too small now.

I don't see how fork would exacerbate any problem here as Corinna
concluded in the email that you cite since it seems like no destructors
would or should ever be called by fork().
