Subject: perl 5.8.0 debugger requires double ENTER key to act on commands: cygwin 1.3.22
To: cygwin AT cygwin DOT com
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii

After upgrading from cygwin 1.3.20 to cygwin 1.3.22,
the new version of Perl (5.8.0) appears to require 2
ENTER keys to be hit for any command to be acted on by
the Perl debugger. The previous version of Perl
(5.7.x) on cygwin 1.3.20 did not have this problem.

Example session:

=====================================================
gavin AT reptilicus /cygdrive/c/cadzilla/cygwin
$ uname -a
CYGWIN_NT-5.0 reptilicus 1.3.22(0.78/3/2) 2003-03-18
09:20 i686 unknown unknown
Cygwin

gavin AT reptilicus /cygdrive/c/cadzilla/cygwin
$ perl -v

This is perl, v5.8.0 built for cygwin-multi-64int

====================================================

For the example Perl debugging session above, the "s"
and "q" commands had no effect after the first ENTER
key was hit. I had to hit the ENTER key a second time
for the debugger command to be acted on.

I'm running W2K. I've rebooted since installing
1.3.22, and the problem still occurs.

Any suggestions on how to resolve this problem?
