#819: Getting references to Method instances leads to segfault -------------------------------------+-------------------------------------- Reporter: eloy.de.enige@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: -------------------------------------+-------------------------------------- As discussed with Laurent, it was hard to reduce the problem. Hence, here are the steps to take, to run a spec which shows the problem: {{{ % git clone git://github.com/alloy/interactive-macruby.git im % cd im % git checkout 966e48cd04e1ee77630869af7f75c356cd106981 % env DYLD_LIBRARY_PATH=../macruby gdb --args macruby -I /Library/Ruby/Gems/1.8/gems/mspec-1.5.17/lib /usr/bin/mspec-run spec/node_spec.rb }}} (You need the mspec gem installed and adjust the paths in the last line accordingly.)
