(Keywords: assertion)
1. Set devtools.chrome.enabled to true
2. Using the web console on a chrome page,
Components.utils.getJSTestingFunctions().enableSPSProfiling()
Result:
Assertion failure: *(int*)size_ >= 0, at /Users/jruderman/trees/mozilla-central/js/src/vm/SPSProfiler.cpp:247
(This function lives in TestingFunctions.cpp, so I assume it's intended for both shell and browser fuzzing.)

It looks like we're switching pseudostacks with frames still present on the old stack; later they try to pop themselves off of the new stack, which does not work. I think |enableSPSProfiling| should either stay on the old stack if one is present, or (if that's infeasible or undesirable) throw an exception in that case.
Hi Jesse,
issue is not reproducible via provided steps, in Windows 10, on Firefox Release 89.0.2 (64-bit) and Nightly 91.0a1 (2021-06-25) (64-bit) versions. Please, @Jesse , can you confirm if you are still experiencing the issue?
Thanks in advance.
Jerónimo.

Hi,
I'm marking this as Resolved-Incomplete due to lack of response. If the issue is still reproducible with the latest Firefox version, feel free to reopen the bug with more information.
