Thanks. The good news is that I can easily reproduce the
problem here (with e.g. ActiveState 5.10.1 on 32-bit Windows XP).
The bad news is that I have no clue what's going on.
Looks like the problem occurs in some END block or in the
global destruction phase. Note that a packed executable actually
runs in a custom Perl interpreter which might have some
problem with the fork emulation on Windows.
I keep looking into this, but don't hold your breadth.
Cheers, Roderich
