Hello Nika, can you please take a look at this? I think this is caused by Bug 1748719.

So, in bug 1748719 I upgraded an assertion from a MOZ_DIAGNOSTIC_ASSERT to a MOZ_RELEASE_ASSERT (https://searchfox.org/mozilla-central/rev/7271a078fa0c1b858a52614ea60ac82fdd8b3d23/xpcom/io/nsStringStream.cpp#365), which should normally be fine, but it appears that we have a test (the test which is failing here) which we have disabled when MOZ_DIAGNOSTIC_ASSERT is enabled as it would normally hit this assertion (https://searchfox.org/mozilla-central/rev/7271a078fa0c1b858a52614ea60ac82fdd8b3d23/xpcom/tests/gtest/TestStringStream.cpp#101-105).

In the patch I wrote the behaviour which could be expected if that assertion was to be ignored has changed somewhat and it wouldn't make much sense for us to ignore the assertion completely anymore. We could possibly drop the test given that it's intentionally hitting this error case, and it's probably not worth the effort to try to make nsStringInputStream gracefully handle API misuse so it's easier to test.

Hello,

We got a new fail (beata as realease simulation) which might be related to Bug 1748719, can you please take a look?
Failure log : https://treeherder.mozilla.org/logviewer?job_id=363993040&repo=try&lineNumber=4312

Nika, could you fix this issue this week?

The behaviour which this test was intended to test was only used in
release builds, due to the diagnostic assertion in other builds. The new
equivalent of this assertion has been upgraded to a release assertion,
so the test should no longer be required.

Oops, I thought I had already submitted my patch for this bug :-S

https://hg.mozilla.org/mozilla-central/rev/3fa2317dc1ca

(This change is test-only so it should be upliftable to beta without a beta approval request.)

https://hg.mozilla.org/releases/mozilla-beta/rev/37285079f8ce

Fix verified in today's central as late beta simulation
