Comment 3

[Lars T Hansen [:lth]]

I guess that's pretty annoying. This is a test for very large webassembly memories and if the test machine is overloaded or underprovisioned it will be easy for it to OOM. I don't think we have a way of catching OOM in the script itself, I'll investigate what the options are.

Comment 4

[Lars T Hansen [:lth]]

Looks like maybe we can use the allow-oom modifier on the test case.

Attachment: Bug 1698984 - Allow large-memory test to oom. r?jandem

This test can oom on some underprovisioned 64-bit platforms like those in our CI,
so allow that as an outcome.
