P.S.: Could somebody please test this in order for me to fix a bug in Bit::Vector? (update)
O. STeffen BEYer
The original bug report reads:
"I tried to install your module Bit::Vector 6.6 (perl v5.8.6 on a PowerPC
G5 Mac Os X v10.4.11) but it failed the test '28___chunklist.t'.
I ran the test outside of Test::Harness, and found it is failing on
the final value of $bits (=33) at $n=97 and $n=99."
The number of bits he indicated is corroborated by the number of tests,
which is 3 * bits. Normally there would only be 96 tests on a 32 bit
machine.
As far as I can remember, I already heard in the past that the Mac was
simulating on more bit when doing bit shift operations (or always regarded
the carry as a additional bit).
Or am I hallucinating this memory?
Paul Schinder just ran the test scripts I sent and everything went fine.
So the results may depend on the version of MacOS or the compiler used.
Thanks a lot for your support!
Best regards,
Steffen

In that case you're posting to the wrong list. This list is for
discussions of MacPerl, a port of perl highly modified to run on the
Mac platform prior to OS X. Since MacPerl hasn't been released since
5.6.2, the bug report can't possibly be referring to it.
