> Hi!
> I'd like to backport this changeset to prevent a crash when AsyncProfiler is used on Mac M1.
>
> The backport is not clean:
> 1. RISCV is not part of jdk17
> 2. mallocTracker.cpp is not updated since 8281023 was not backported to jdk17
> 3. vmError_posix.cpp requires manual update due to 8289350 is missed at jdk19+
> 4. Need to add globals.hpp to fix builds without precompiled headers
>
> There is follow up for this case:
> 1. 8284997: arm32 build crashes since JDK-8283326
> 2. 8288719: [arm32] SafeFetch32 thumb interleaving causes random crashes
