[Andrew McCreight [:mccr8]]

Looks like a possible bug in the JSAPI written for a gtest, so I'm going to unhide this.

Comment 12

[Yannis Juglaret [:yannis]]

I think this use-after-poison when accessing a field on a JSObject* means that the mClean object has been garbage collected before we even reached UntrustedModulesFixture::ValidateJSValue. UntrustedModuleFixtures::Serialize appears to be the only test where we initialize the AutoJSContextWithGlobal from within a subfunction rather than at the top of the TestBody, even though the following comment above the AutoJSContextWithGlobal declaration explicitly states that the AutoJSContextWithGlobal should be put at the beginning of the test:

// AutoJSAPI is annotated with MOZ_STACK_CLASS and thus cannot be
// used as a member of TelemetryTestFixture, since gtest instantiates
// that on the heap. To work around the problem, use the following class
// at the beginning of each Telemetry test.

:willyelm, could someone familiar with AutoJSContext and JS::Rooted review UntrustedModuleFixtures::Serialize to confirm if the difference noted above can explain the issue here?

We are pushing a potential fix with bug 1889839 comment 37 but happy to hear more detailed explanations.

Comment 15

[Jan de Mooij [:jandem]]

(In reply to Yannis Juglaret [:yannis] from comment #12)

:willyelm, could someone familiar with AutoJSContext and JS::Rooted review UntrustedModuleFixtures::Serialize to confirm if the difference noted above can explain the issue here?

That seems plausible because mCleanGlobal isn't rooted, so if a GC happens before the AutoJSContext is instantiated, the global can be collected.

Comment 16

[Greg Stoll :gstoll]

Thanks! The fix :yannis mentioned above does seem to have addressed this (there has been one failure of the test since then but it looks unrelated to this poison problem), so I'm going to close this.
