Jemalloc crashes on M1 Macs, when targeting x86_64, instead of aarch64

[chriphus]

Please have a look at a minimal hello world program to reproduce: https://github.com/chriphus/jemalloc-bug

Jemalloc crashes on M1 Macs when building for an x86_64 target. Note that this bug does not occur when building for an aarch64 target. However, since some of our production software depends on C libraries that currently do not support ARM, we are forced to target x86_64 instead of ARM on the Rust side as well.

The program crashes with Exception: EXC_BAD_ACCESS (code=2, address=0x100f11688) when run from CLion, or terminated by signal SIGBUS (Misaligned address error) when run from command line.

This issue is preventing us from using Jemalloc when building and testing on M1 Macs, however we do use Jemalloc in all other circumstances without issues.

It seems arm64 is not supported right now. I also failed building it on M1 Mac

Thanks,
