Bug #11869: random hang/SegFault when accessing a missing constant in irb

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 2.2.4p230 (2015-12-16 revision 53155) [x86_64-linux]
• Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN

[postmodern (Hal Brodigan)]

While testing ruby-2.2.4 on Fedora 22, I noticed that sometimes ruby would hang or segfault when accessing a missing constant within irb.

Steps to Reproduce

1. /path/to/ruby-2.2.4/bin/irb
2. type "FOO" and press enter
3. Repeat step 2 until irb hangs or segfaults

Results

Here is the backtrace from an immediate segfault:

/home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb/input-method.rb:150: [BUG] Segmentation fault at 0x00000000000008
ruby 2.2.4p230 (2015-12-16 revision 53155) [x86_64-linux]

Ruby 2.2.4 was compiled against the system's readline-6.3 (5.fc22) package.

[lamont (Lamont Granquist)]

I'm seeing this on debian 7, rhel 6, and ubuntu 14.04 at least (but running binaries compiled on debian 6, rhel 5, and ubuntu 10.04, respectively). The chef rspec test suite triggers this:

git clone https://github.com/chef/chef
cd chef
rspec spec/functional/shell_spec.rb
( run repeatedly )

I definitely do not observe this failure on Mac OSX 10.11.2 with rvm installed 2.2.4 (having run the rspec suite many dozens of times on 2.2.x and never seen a seg fault here).

A gcc vs. clang compiler difference? Some gcc optimization that causes it to fail? Seems consistent across a wide range of gcc versions from 3.x to 5.x if that's the case. It seems to only affect linux, but that might be an effect of our running more tests against linux than solaris/freebsd/etc.

[lamont (Lamont Granquist)]

I built our whole system (ruby, libedit, ncurses, etc) without any optimizations at all and got a build that passed our specs.

I tried dropping the optimization down to -O2 from the -O3 we had been using, along with bumping libedit from 20120601-3.0 to 20150325-3.1 and ncurses from 5.9 to 6.0-20150810 and still got one failure on debian-6 in the same spec test but a "memory corruption error" from malloc() this time:

1. Shell smoke tests sets the override_runlist from the command line
   Failure/Error:
   raise "did not read expected value #{expected_value}' within #{TIMEOUT}s\n" + "Buffer so far: #{buffer}'"

   RuntimeError:
   did not read expected value => "done"' within 300s Buffer so far:
   ["override::foo", "override::bar"]
   => nil
