Bug #1856

Updated by jeremyevans0 (Jeremy Evans) over 4 years ago

=begin 
  
  I have a 120 line pure ruby application that bombs out in 1.9.1p129 after 1-2 seconds with a [BUG] Segmentation fault & [BUG] object allocation during garbage collection phase. 
 
  I'm using a piece of code that I got from Ruby Treasures which has worked fine in 1.8.X for a long time. I'm going through the process of porting to 1.9.1. I've inlined this code, and my little app that uses it is at the bottom. 
 
  The error output I see is: 
 
  seg-fault.rb:115: [BUG] Segmentation fault 
  ruby 1.9.1p129 (2009-05-12 revision 23412) [i686-linux]
