Details

Today I noticed that Firefox with lazy tiering enabled crashes on the PSPDFKit WASM benchmark, which it didn't do a few days ago.

STR: In a new profile, switch javascript.options.wasm_lazy_tiering to true. Load https://www.nutrient.io/webassembly-benchmark/ .

AR: The tab crashes in sub-benchmark 2 "Search a term".

ER: No crash, like a few days ago.

Here's a crash id: https://crash-stats.mozilla.org/report/index/60e82f6e-e457-4b0a-8145-f9a6b0250306

Mozregression points to bug 1861078 as the regressor.

This should now be fixed in the current version of nightly.
