Description

#818 also reminds me of another thing: some clang distribution may enable things like -ftrivial-auto-var-init=pattern (and -fstrong-stack-protector) enabled by default, we may want to examine the performance impact and opt out such hardening from the routines where they may cause performance issue.

Research direction

Start by reviewing issue #818 and the compiler configurations that enable -ftrivial-auto-var-init=pattern or -fstrong-stack-protector. Identify the affected allocator routines, measure their performance impact, and report which hardening options, if any, warrant scoped opt-outs.
