Description

Issue: Segfault on OSX when using ffi-aspell set method

Reproducable test case:

require 'ffi/aspell';speller = ::FFI::Aspell::Speller.new('en_US');speller.set('mode', 'html');puts speller.correct?('foo');

Expected behaviour:

$ ruby -e "require 'ffi/aspell';speller = ::FFI::Aspell::Speller.new('en_US');speller.set('mode', 'html');puts speller.correct?('foo');"
true

Actual behaviour:

$ ruby -e "require 'ffi/aspell';speller = ::FFI::Aspell::Speller.new('en_US');speller.set('mode', 'html');puts speller.correct?('foo');

Abort trap: 6

Setting the mode is the reason it segfaults. Without the mode it's fine:

$ ruby -e "require 'ffi/aspell';speller = ::FFI::Aspell::Speller.new('en_US');puts speller.correct?('foo');"
true

I've attached the crash log.

This appears to affect all rubies. Tried with rbenv:

  • system
  • 2.1.10
  • 2.2.5
  • 2.3.3
  • 2.4.0

This appears to only affect OSX., I tried on an Ubuntu 16.04 machine and it worked fine:

$ uname -a 
Linux ubuntu-test 4.4.0-64-generic #85-Ubuntu SMP Mon Feb 20 11:50:30 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
$ ruby --version
ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]
$ ruby -e "require 'ffi/aspell';speller = ::FFI::Aspell::Speller.new('en_US');speller.set('mode', 'html');puts speller.correct?('foo');"
true

A bug in ffi-aspell or (less probably) aspell library.
FFI can very easily cause segfault.
