Just those two lines? What if you use LWP::UserAgent instead of WWW::Mechanize? If you get the memory read error there, too, then it's not WWW::Mechanize's fault.

I suspect the problem is with Clone. Can you please investigate this further by: 1) Try using "use Clone" instead of "use WWW::Mechanize" and see if that crashes. 2) Comment out the line in Mechanize.pm that has "use Clone", and try the original "use threads; use WWW::Mechanize;" two-liner. Thanks, Andy

I'll let you do it. I've been meaning to remove the dependency on Clone anyway (ticket #1709). Thanks for bein' Mr. Research on this.

WWW::Mechanize no longer uses the Clone module as of 0.37. Let's hope this thread problem goes away.
