Issue descriptionUserAgent: Mozilla/5.0 (X11; Linux x86_64; rv:62.0) Gecko/20100101 Firefox/62.0 Steps to reproduce the problem: 1. Open "bug.html" 2. Execute the following actions in the debugger, where the first column is the action, the second the line and the third the column: set_bp 153 17 Reload page set_bp 173 19 set_bp 74 5 step_out step_in step_over step_over step_over step_over continue What is the expected behavior? The debugger should not pause after the last "continue" action. What went wrong? The debugger paused at a location w/o a BP after a continue. Did this work before? N/A Chrome version: Version 69.0.3497.100 (Official Build) Channel: stable OS Version: Arch Linux x64 Flash Version: n/a See devtools.mkv for video of actions. Excuse the non-minized JS, I wasn't sure which prerequisites have to be met to trigger this bug.

I was able to further minimize the actions. The required actions are: set_bp 180:12 reload set_bp 74:5 step_over continue The debugger then stops at 186:1, same as before. I also noticed that the test execution is in fact incorrect (according to test262). I reported this at #8415 in the v8 bugtracker. https://bugs.chromium.org/p/v8/issues/detail?id=8415

I have not tested this on latest dev version, however I verified that the bug still exists in version 70.0.3538.102. Also, you need to load the script via the min.html file, accessing the .js file directly doesn't work.
