Hi Paul, can this be a regression of bug 1743781?

Flags: needinfo?(pbone)
Summary: Intermittent Assertion failure: topSize == exSize, at /builds/worker/checkouts/gecko/xpcom/base/nsMemoryReporterManager.cpp:537 → High frequency Assertion failure: topSize == exSize, at /builds/worker/checkouts/gecko/xpcom/base/nsMemoryReporterManager.cpp:537
See Also: → 1777370

That shouldn't happen...

Assignee: nobody → pbone
Status: NEW → ASSIGNED
Flags: needinfo?(pbone)
OS: Unspecified → macOS
Priority: P5 → P1
Hardware: Unspecified → x86_64

I developed this on a Mac M1. I suspect that for some reason the memory maps don't match on x86_64. I can try and find out why but the first step is to remove the assertions and let people get on with their non-crashy lives.

Summary: High frequency Assertion failure: topSize == exSize, at /builds/worker/checkouts/gecko/xpcom/base/nsMemoryReporterManager.cpp:537 → High frequency Assertion failure: topSize == exSize (and others) at /builds/worker/checkouts/gecko/xpcom/base/nsMemoryReporterManager.cpp:537

Now that we know these assertions fire, we can remove them.
