Hello, again! The following fails on ruby 1.7.1 (2001-06-22) [i686-linux] and ruby 1.7.1 (2001-07-03) [i686-linux] - seems some sort of buffer overrun or such. strace results and other debug info are available by request. xm@ns:~/ruby/test$ ruby -e "File.expand_path '1'*4096" -e:1: [BUG] Segmentation fault ruby 1.7.1 (2001-06-22) [i686-linux] Aborted Also, probably I should report things like this to ruby-dev or such? (sorry - just don't know the normal practice for that) Aristarkh A Zagorodnikov, Lead Programmer, W3D Group http://www.w3d.ru /// xm / w3d.ru /// ICQ UIN 36987938
