@senorblanco  -- Could you please look into this issue, kindly reassign if it has nothing to do with your changes.

Note: CC'd the suspects given by the Predator results.

Thank You.

Note that I couldn't repro this in a dev build of M65 Windows or Linux.

However, I'm guessing that whatever linux ARM device generated this (maybe Android) has a smaller stacksize. I was able to repro on Linux by using "limit stacksize 1024" .

It seems to be fixed by https://skia-review.googlesource.com/c/skia/+/92721, soon to roll into Chrome.
