#992: dynamic string in thread, in block causing a segfault -------------------------------------+-------------------------------------- Reporter: mattaimonetti@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: MacRuby 0.8 Component: MacRuby | Keywords: -------------------------------------+-------------------------------------- The following code triggers a segfault: {{{ def slow_operation(n); end n = 10 ths = [] 10.times do |n| ths << Thread.new{slow_operation("thread #{n}")} end; ths.each{|t| t.join} }}} Renaming or removing the n variable fixes the problem. Offline Laurent said: You build a dynamic string "thread #{n}" inside a thread. n refers to the block dvar or, at one point, we leave the times loop before the thread starts to use the variable -- Ticket URL: <http://www.macruby.org/trac/ticket/992> MacRuby <http://macruby.org/>
