Can't hijack Rails 3 process running under Ruby 1.9.2

[dolzenko]

Here is the output I get running hijack --gdb-debug command on Rails 3/Ruby 1.9.2 process:

...

(gdb) break rb_trap_exec

(gdb) continue

Obviously nothing happens afterwards.

PS. It looks like rb_trap_exec was removed in this commit http://redmine.ruby-lang.org/repositories/diff/ruby-19/signal.c?rev=19080
