In reading Jakob's response
(https://groups.google.com/g/v8-dev/c/7ZI3vxtabcU/m/c9qvHkOBBAAJ), I'm
interpreting it slightly differently-
He says that raising the stack limit *is* safe for 32-bit ARM, even
inside of the V8 upstream source tree.
For ARM64, he says that raising the stack limit is not safe for v8
*embedded inside WebView*, and therefore not appropriate for upstream
v8. But then he says it could/should be safe for v8 *embedded inside
NodeJS*.
Based on that, I suggest patching Debian's NodeJS with the patch to
adjust armhf/arm64 stack limit size to 984kb. With the caveat that the
javascript code that is triggering this bug should really be fixed to
not be so stack-intensive, of course. Perhaps this bug cloned at a
lower severity, filed against those packages that this bug is affecting?
(As chromium maintainer, which also embeds v8, I haven't heard of any
issues and hadn't planned on touching stacks limits. It sure would be
nice to have just one copy of V8 in the archive, though..)
