Created attachment 52997 [details] Simple test case 1. Set a breakpoint at the var foo = "bar" line in the attached test case 2. Refresh Result: Breakpoint is no longer listed and is never hit. Throbber is still throbbing. Expected result: breakpoint remains and is hit. Seen in Chrome 5.0.360.0 (Official Build 42309) dev on Windows Vista.
Works fine on WebKit. Is likely to be a Chromium issue. This script is getting collected momentarily too, so you will see all kinds of strange things related to it.
Reopening. I hit this all the time. Why was this closed? I put the [Chromium] in the subject to make it clear it's a chromium bug.
Chromium and V8 have left the building. Won't fix.
