I cannot reproduce the problem with `-Xjit:limit=m1,optlevel=noOpt`, but with `-Xjit:limit=m1,optlevel=cold`. The trace file with the noOpt level has the node `istore ArrayCopyTest.sum I`, but at the cold level the node...

@jmesyou Attached please find my JIT trace files for noOpt and cold. [19247.zip](https://github.com/eclipse-openj9/openj9/files/14878024/19247.zip) There is no store to `ArrayCopyTest.sum` after localValuePropagation in m1-cold.txt. I used the following command lines: -...

OpenJ9 for AArch64 macOS does not support native stack backtrace: Issue #15925. It is not supported on x86 macOS, either.

I ran two 30x Grinder jobs, and got one failure: https://openj9-jenkins.osuosl.org/job/Grinder/3758/ https://openj9-jenkins.osuosl.org/job/Grinder/3759/ ``` HHLT stderr Unhandled exception HHLT stderr Type=Segmentation error vmState=0x00000000 HHLT stderr J9Generic_Signal_Number=00000018 Signal_Number=0000000b Error_Value=00000000 Signal_Code=00000002 HHLT stderr...

@gacholio Because no one has implemented it for macOS (neither x86 nor AArch64) yet. Issue for AArch64 macOS: #15925

Any reports of reproducing this issue on platforms other than AArch64 Linux?
