I ran into this problem as well, with bash-2.03. I do not know if there
are any special compile-time directives that will correct this problem;
I reverted to the cygnus-distributed bash-2.02, which fixed the problem.

I haven't seen any of these problems, and I've built every perl from
5.5.640 to 5.6.0-RC1. Generating the initial perl.dll does take a long
time (3-4 minutes on my K6 200). Just let it run to completion?

Are you sure this is not related to the binmode pipe problem you
described earlier?
