[wxruby-users] object allocation during garbage collection phase

[Niklas Baumstark]

Hello,

when i run the bigdemo sample, the app crashes initially after opening the "tip of the day" (it doesn't when i don't touch mouse and keyboard). can't even get to the main window. i ran it in gdb, it gives me the following trace:

Starting program: /usr/local/bin/ruby bigdemo.rb

$ ruby -v
ruby 1.8.7 (2008-08-02 revision 0) [i686-linux]

don't know if this is a bug, maybe its my own fault. i don't really need the bigdemo so it's no problem for me, but maybe the wxruby devs are interested.

i remember that it was working when i compiled ruby (same version) without pthread support, maybe this is the prob (ruby 1.8.6 worked even with pthread support). if you need further info, please tell me.

Greetings,
Niklas
