1763315 - Assertion failure: gcTotal == rtStats.gcHeapChunkTotal when generating a memory report

Status: RESOLVED WORKSFORME

(Core :: XPConnect, defect, P2)

Description

[Paul Bone [:pbone]]

STR:

• In a built with assertions
• open: https://www.fastcompany.com/90732166/what-happened-to-starbucks-how-a-progressive-company-lost-its-way?utm_source=pocket-newtab-intl-en
• wait for the page to load. scroll down somewhat as if reading the article, the crash is intermittent, this seems to help.
• In a new tab, open about:memory and click Measure.
• Observe that the first tab has crashed.
• If it didn't crash scroll a little further/wait/wait for some other elements to come in (I don't know the cause) then click "Measure" in about:memory again.
