From: lamont@... Date: 2016-01-30T16:29:44+00:00 Subject: [ruby-core:73605] [Ruby trunk - Bug #11869] random hang/SegFault when accessing a missing constant in irb Issue #11869 has been updated by 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 *** glibc detected *** ruby: malloc(): memory corruption: 0xb6c8d008 *** ======= Backtrace: ========= /lib/libc.so.6(+0x6adba)[0xb73c2dba] /lib/libc.so.6(+0x6dbd7)[0xb73c5bd7]

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] -- Control frame information ----------------------------------------------- c:0023 p:---- s:0085 e:000084 CFUNC :readline c:0022 p:0042 s:0080 e:000079 METHOD /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb/input-method.rb:150 c:0021 p:0011 s:0076 e:000075 BLOCK /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb.rb:469 c:0020 p:0040 s:0073 e:000072 METHOD /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb.rb:623 c:0019 p:0009 s:0068 e:000067 BLOCK /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb.rb:468 [FINISH] c:0018 p:---- s:0066 e:000065 CFUNC :call c:0017 p:0015 s:0063 e:000062 METHOD /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb/ruby-lex.rb:188 c:0016 p:0015 s:0059 e:000058 METHOD /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb/ruby-lex.rb:103 c:0015 p:0022 s:0055 e:000054 METHOD /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb/slex.rb:205 c:0014 p:0042 s:0047 e:000046 METHOD /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb/slex.rb:75 c:0013 p:0044 s:0042 e:000041 METHOD /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb/ruby-lex.rb:282 c:0012 p:0013 s:0038 e:000037 METHOD /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb/ruby-lex.rb:264 c:0011 p:0022 s:0033 e:000032 BLOCK /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb/ruby-lex.rb:235 [FINISH] c:0010 p:---- s:0030 e:000029 CFUNC :loop c:0009 p:0007 s:0027 e:000026 BLOCK /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb/ruby-lex.rb:231 [FINISH] c:0008 p:---- s:0025 e:000024 CFUNC :catch c:0007 p:0015 s:0021 e:000020 METHOD /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb/ruby-lex.rb:230 c:0006 p:0030 s:0018 E:000a80 METHOD /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb.rb:485 c:0005 p:0008 s:0015 e:000014 BLOCK /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb.rb:395 [FINISH] c:0004 p:---- s:0013 e:000012 CFUNC :catch c:0003 p:0143 s:0009 E:0002d0 METHOD /home/hal/.rubies/ruby-2.2.4/lib/ruby/2.2.0/irb.rb:394 c:0002 p:0021 s:0004 E:001a10 EVAL /home/hal/.rubies/ruby-2.2.4/bin/irb:11 [FINISH] c:0001 p:0000 s:0002 E:001520 TOP [FINISH] -- Ruby level backtrace information ---------------------------------------- /home/hal/.rubies/ruby-2.2.4/bin/irb:11:in `
