Start with the stack trace locations in third_party/mimalloc/src/random.c:265 and third_party/mimalloc/src/init.c:141-144, then inspect how initialization interacts with AddressSanitizer before main(). Reproduce with mimalloc v1.6.7 on Ubuntu Linux 5.9 using gcc 10.2.0; done means the crash no longer occurs before main().
