Seg fault on Thread.new with ruby 1.8.6

Ruby

Hi all,

Since my rails app crashed, I cannot restart it and get the following
error at startup:

/local2/ruby/gems/gems/rails-2.1.1/lib/commands/servers/base.rb:4: [BUG]
Segmentation fault
ruby 1.8.6 (2008-08-11) [i386-linux]

I have ruby 1.8.6 on 32-bit linux and found out that the error actually
occurs when attempting to create a new thread with ‘Thread.new do …’.

Do you have any idea on how to debug/solve this problem ?

Thx

try different version of rails.
