Next command is leaving current stack frame

[jmondo]

when I hit next (or n) it should "Step over to the next line within the same frame" but when I hit next a few times it leaves the current frame and jumps into activerecord source. This happens under MRI 1.9.3 and 2.0.0

here's the recording: http://showterm.io/b3f3cd8e525b69d803e98

other relevant stuff. it's a skeleton rails app with 1 model and these gems:

oh and meanwhile with pry-byebug with MRI 2.0.0p247 it seems to be working how I would expect (not jumping into activerecord)

Here's the project if you want to replicate: https://github.com/jmondo/debugpry Be sure to run Book. seed_books

Having this same problem with the finish command. It jumps down into the next stack frame instead of up after the current frame returns.

Also, possibly related: pry-stack_explorer's show-stack command is just giving me No caller stack available!. I'm also experiencing the same issue with pry-byebug.
