The following minimal application gives a segfault at exit when the
GC.stress line is uncommented. Any clues on how to debug this? Thanks!
begin
require ‘rubygems’
rescue LoadError
end
require ‘wx’
GC.stress = true
class ClipError2 < Wx::Frame
def initialize(parent)
super
end
end
Wx::App.run do
frame = ClipError2.new(nil)
frame.show
end
Here are the details of my environment.
