Thanks for reaching out! Indeed, preserve_most support turned out to be a bit incomplete, so we tried to restrict it to the most important platforms and toolchains used for Chromium. It's restricted to clang anyway, and I didn't find any relevant fixes since the introduction in 2016. Which toolchain do you use where you see crashes? Maybe we can restrict it further to the most recent clang versions.
