Get a trace from a 'stack too deep' error in Rails

trace.rb

$enable_tracing = false
#$trace_out = File.open(Rails.root + 'trace.txt', 'w')

set_trace_func proc { |event, file, line, id, binding, classname|
  if $enable_tracing && event == 'call'
    #$trace_out.puts "#{file}:#{line} #{classname}##{id}"
    raise "crash me" if caller_locations.length > 500
  end
}

$enable_tracing = true

@badbabykosh it's been a long time since I used this initialiser. It should only be necessary if for some reason you haven't got the backtrace already. Stack overflows are nearly always caused by recursive loops, so you should see repeats of the same method sequence over and over in the backtrace.
