Has anyone been able to reproduce this? I get the same crash with any
snapshot later than 20050311 (the 20050311 snapshot itself is fine). I
suspect this may be due to the following change:
<http://cygwin.com/ml/cygwin-cvs/2005-q1/msg00202.html>
I'll investigate further, but it would be nice to get this confirmed.
Here is the command I used to reproduce this:
perl -MNet::FTP -e '$a=Net::FTP->new("cygwin.com")->ls("/");'
"uname -srv" reports "CYGWIN_NT-5.1 1.5.14s(0.124/4/2) 20050316 16:53:05".
Perl is version 5.8.6-4. Anyone?
Igor
