Hello, there’s a simple script require ‘rubygems’ require ‘mysql’ require ‘mechanize’ #it works if I delete this string m = Mysql.new(‘localhost’, ‘h3’, ‘h3’, ‘h3’) that fails with C:/Program Files/ActiveState Komodo IDE 5/lib/support/dbgp/rubylib/rdbgp/processor.rb:370: [BUG] Segmentation fault ruby 1.8.6 (2008-08-11) [i386-mswin32] but, doesn’t fail if I comment out the string requiring mechanize. How can I fix it? TIA ---

I am having the same problem in 1.9 however I don’t use mechanize. My script worked fine in version 1.8.6 but after the upgrade generates a segmentation fault: C:/Program Files/ruby-1.9.1/lib/ruby/gems/1.9.1/gems/mysql-2.7.1-x86-mswin32/ext/mysql.so: [BUG] Segmentation faul ruby 1.9.1p0 (2009-01-30 revision 21907) [i386-mswin32] ## – control frame ---------- c:0005 p:-2710104 s:0031 b:0031 l:000030 d:000030 TOP c:0004 p:---- s:0029 b:0029 l:000028 d:000028 CFUNC :require c:0003 p:0023 s:0025 b:0025 l:000e5c d:000168 EVAL lib/rssbuilder.rb:5 c:0002 p:---- s:0004 b:0004 l:000003 d:000003 FINISH c:0001 p:0000 s:0002 b:0002 l:000e5c d:000e5c TOP :427 – Ruby level backtrace information----------------------------------------- lib/rssbuilder.rb:5:in `require' lib/rssbuilder.rb:5:in `’ [NOTE] You may encounter a bug of Ruby interpreter.

There are no binaries for the Windows version greater than 1.9.1. I tried installing 1.8.7 but the windows distribution seems incomplete. Other scripts work fine in 1.9.

Also, did you build from source mysql gem? AFAIK the binary version of mysql gem is _only_ for 1.8, and can’t work with 1.9 without being recompiled and linked to Ruby 1.8 runtime/ shared library. ---
