1408558 - 500ish bytes leaked of various a11y stuff in mochitests on win32 and win64 in tab process

Status: NEW

(Core :: Disability Access APIs, defect, P2)

Description

[Andrew McCreight [:mccr8]]

This small leak shows up in a few different mochitests.

leaked 1 Accessible
leaked 1 HyperTextAccessible

(There are a few other things leaking, but they show up in all win32 content processes.)

It seems like maybe this is showing up during this test:
accessible/tests/browser/e10s/browser_caching_description.js

Or maybe this is related to the preallocated process manager or something, because that's an early test (but not the first).

There's a similar thing with accessible/tests/browser/tree/browser_aria_owns.js and as I said, other tests.

I think this is the same issue we looked at a month ago or so, related to querying interface method https://dxr.mozilla.org/mozilla-central/source/ipc/mscom/Interceptor.cpp#610-626

Here's earlier discussion in IRC: http://logs.glob.uno/?c=mozilla%23accessibility&s=25+Aug+2017&e=25+Aug+2017#c161332
Aaron had a patch for me to try but iirc it did not fix the issue. ni? aaron in case he might have some thoughts.
