Comment (by MarcusCalhoun-Lopez):

 I built jemalloc on both an x86_64 machine and on an Apple Silicon machine
 with `build_arch=x86_64`.\\
 The only difference I could find was `#define CPU_SPINWAIT __asm__
 volatile("pause")` on the actual x86_64 machine.\\
 That particular difference went away went I used version 1.1 of the
 muniveral PG.\\
 I have no idea if that is the cause of the problem, but it might be worth
 a look.\\
 Unfortunately, I cannot test it at the moment, but there is a
 [https://github.com/macports/macports-ports/pull/17149 pull request] with
 what I tried.
