1600264 - intermittent mochitest crashes on local debug builds ("process() called before end")

Status: RESOLVED DUPLICATE of bug 1595936

(DevTools :: Responsive Design Mode, task, P3)

Description

[Julian Descottes [:jdescottes]]

I noticed that RDM tests are frequently failing on my machine when running in debug mode (macos artifact builds).

For reference my current central rev is https://hg.mozilla.org/mozilla-central/rev/79c674504d23

STRs:

• enable debug build
• clobber, build
• ./mach test devtools/client/responsive/test/browser/browser_device_custom_edit.js (or any other test)
• repeat last step a few times if it doesn't crash immediately (I get crashes ~30% of the time)

Will attach the logs of a failure.
