1582088 - Watchpoint disappears after resume

Status: RESOLVED DUPLICATE of bug 1604865

(DevTools :: Debugger, defect, P3)

Description

[Jan Honza Odvarko [:Honza] (always need-info? me)]

This is weird, since it works on other test page, but here are the STRs:

1. Load https://dbg-mutation.glitch.me/
2. Create BP on line 9 in client.js
3. Hit the stuff button, break in debugger
4. Create set WP for obj.b
5. Resume three times (twice on the WP once one debugger; statement)
6. Remove the BP on line 9
7. Hit the stuff button, Debugger doesn't break on the WP -> BUG

ER: the WP should still be there and the Debugger should pause on it.

Also, the WP isn't there anymore.

I am on Win10 + Nightly

The reason for that is that the watchpoint is associated with a local variable obj which is GCd when you leave the stuff function.
