Possible STR:
What steps will reproduce the problem?

Run a Rails server in debug mode
Visit http://localhost:3000
Visit http://localhost:3000 again

What is the expected result?
The page should load.

What happens instead?
The IDE is at a breakpoint within Rails, though I did not set the breakpoint.

the problem might be caused by https://bugs.ruby-lang.org/issues/11492 (in this case everything should work with ruby-head) If it doesn't work please add Debase.verbose to true (somewhere at the beginning of rails loading) and it will provide huge output with all events. Please send the output and I will try to understand what goes wrong.

Oleg Sukhodolsky · Answer 2 · Tue Dec 01 2015 14:13:43 GMT+0800 (China Standard Time)

@denofevil it looks like the fix for 11492 has been backported to 2.1.x too (should be available in 2.1.8)
Perhaps we can close the ticket or do you wont to invent the way to workaround possible bugs in trace API? ;)
