Looks like this bug (1734421) is an error when there is no space to create an rlbox sandbox, while the other bug mentioned (bug 1733686) is to do with the sandbox internally running out of memory. @glandium In the case of the most frequent x86 32bit platform crashes, I think the fix is in "part 1 of Bug 1728934" (which we couldn't land in time for this cycle). That patch ensure we make better use of the limited available virtual memory in 32-bit applications. I will need to look more into the one or two x64/arm64 related crashes here.
