[ruby-core:44672] [Ruby 1.8 - Bug #6366] Regex freezes Ruby

From: "vertis (Luke Chadwick)" <luke.a.chadwick@...>
Date: 2012-04-27 03:36:49 UTC
List: ruby-core #44672
Issue #6366 has been updated by vertis (Luke Chadwick).


Sure, that works. You're absolutely correct about my regex error. However, I still think it's a bug. The behaviour should be to fail with an Exception not lockup indefinitely.
----------------------------------------
Bug #6366: Regex freezes Ruby
https://bugs.ruby-lang.org/issues/6366#change-26237

Author: vertis (Luke Chadwick)
Status: Rejected
Priority: Normal
Assignee: 
Category: 
Target version: Ruby 1.8.7
ruby -v: ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-darwin11.3.0]


I stumbled across a weird error on Ruby 1.8.7p352, where String.match locks up:

"#^(?:export)?\s*(\w+)=(.*)".match(/^(?:export[\s]+)?([\w_]*)+?=(.*)/)

I had, apparently, pasted a regular expression into a file(bash) that I was testing, and commented it out. I'm assuming I did this to clear my clipboard. I was then running the following match on each line in the file & consistently had the ruby interpreter lockup (not even Ctrl-C was working, though Ctrl-Z did).

I have replicated this on both MacOS (homebrew) and CentOS 6 1.8.7p352, but this doesn't happen in Ruby 1.9.2p0.
