[Alexandru Michis [:malexandru]]

Jan, could you please take a look?

Comment 2

[Jan de Mooij [:jandem]]

Oh this is TSan, we just have to disable the test for that (TSan doesn't like big allocations, we had the same issue for JS shell tests).

I'll post a patch soon.

Attachment: Bug 1692006 - Disable test_arraybufferinputstream_large.html for TSan. r?jmaher!

I added this test recently in bug 1674777. It allocates a huge ArrayBuffer and
TSan doesn't like that, we had the same issue with JS shell tests for this.
