Hi John, I'm using assert() to check some of the conditions in my code before I start the event loop and noticed that when the script exits after "require 'wx'", but before the main loop is started, it triggers segfault on Linux (tested on Fedora 18, but I saw the same thing on Ubuntu).
The script is as simple as one line with require 'wx'. Adding one more line causes various segfaults that all seem to be originating from wxLuaStateRefData::CloseLuaState; the results are shown below. I'd appreciate any insight into what may be causing this or how to fix it. Thank you.
