ruby-core

Moi,

the following is probably not a ruby problem, but rather something I do 
in my extension.
My question is just, how do I debug such a problem ?

Any help appreciated

Torsten

PS:The "Recovering" lines are where I use rb_intern, with the given 
symbol
PPS: I'm not sure when my recovery code runs, but by the looks of it 
maybe before the full parsing is done.


(gdb) run -d test/all.rb
Starting program: /usr/local/bin/ruby -d test/all.rb
