Problems with Perl LWP and CYGSSL.DLL

Problems with Perl LWP and CYGSSL.DLL

I'm having problems using LWP.pm (libwww extension for Perl) with my cygwin Perl
binary.  Errors are generated each time I try to run Perl code which uses the
LWP library to make a GET or POST request for an https (SSL) web location. The
errors appear to complain that there is a Win32 error with Perl or CYGSSL.DLL
(or both?)

The errors aren't fatal, but they constitute the entirety of the output
generated by the script.  Unless I kill it, the executing process just keeps
chugging along, consuming 100% CPU and sending a new error message to STDERR
about every 5 seconds.  The same code runs flawlessly for non-SSL requests.

How do I go about fixing this?

Looks like the problem which was discussed in another thread recently,
C. Faylor suggested that there may be two (different) cygwin1.dll's on
your system.

You know that you are still using
"This is perl, v5.6.1 built for cygwin-multi"
but also have  C:\cygwin\bin\cygperl5_8_0.dll
installed?

Which from the SSL modules do you use?
There are two possibilities, I installed Crypt::SSLeay (0.45)
to do the test which works for me with perl-5.8 (NT4):

Thank you for your help!  I'm sorry, I don't really understand though.  Do you 
mean rebuild them?

Thanks for the tip.  This proves to be true in my case.  I actually found THREE 
cygwin1.dll's on my system!

Yes, this is true.  Perl 5.8 has been acting very strangely for me, so I moved 
back to 5.6x

> Which from the SSL modules do you use?

I use all of the modules from the 5.6 installation.  It still looks in the 
default installation-specific paths, so it is not using the modules from 5.8 AFAICT.

Thanks for the tip!  Am so doing :O)

I appreciate your help.  Thanks again for letting me know about these issues.  I 
had not been aware of them.
