Arai, could this be related to Bug 1786834 ?

So far the problem seems to be related to Windows 11 x64 22H2 CCov WebRender opt Xpcshell tests test-windows11-64-2009-ccov-qr/opt-xpcshell X5.

This might be related with the fact that in CCov builds we might have to keep the children process around to captured the code coverage content. Maybe this has an impact on the shutdown as well as the ref-count of shared immutable strings, which combined with some non-properly terminated runs holds the string cache for too long.

it's strange that, now SharedImmutableStringsCache::free is called only when there's no live runtime.
(which had been a problem with leaked runtime case in reftest)

https://searchfox.org/mozilla-central/rev/1cae9ca7cc7d17cfc92088dfc68e5ff391128caa/js/src/vm/SharedImmutableStringsCache.cpp#127-129

void SharedImmutableStringsCache::freeSingleton() {
  if (!JSRuntime::hasLiveRuntimes()) {
    singleton_.free();

So, if the assertion fails, it means there's no live runtime but the string is somehow kept alive.

anyway, I'll experiment with adding debug dump.

looks like the following content script and its URL is kept alive.

the raw script source string is held by Stencil, and it's freed when compressing the source, or when a PrecompiledScript is deleted,
and the latter seems to be suspicious.
I'll check if all PrecompiledScript is deleted until that point.

https://searchfox.org/mozilla-central/rev/b741ddde6c678ca7025858952202d20664491555/js/xpconnect/loader/PrecompiledScript.h#27,55

class PrecompiledScript : public nsISupports, public nsWrapperCache {
...
  RefPtr<JS::Stencil> mStencil;

it looks like a stencil is created off-main-thread during shutdown.
that would mean that AsyncScriptCompiler's off-thread compilation task should is running while JS_Shutdown is called.
we should join AsyncScriptCompiler tasks before shutting down.
