Crash in ArmPL zdot_conj_kernel

I have been using ArmPL on Linux for quite some time. I have experienced  numerous mysterious sporadic crashes which I haven't been able to identify the cause for. Recently, I started using ArmPL on macOS too and the same type of crashes started occurring on that platform as well. At first, I thought that the issue was related to the OpenMP library but after some experimenting I came to the conclusion that the crash is related to ArmPL. Here is my setup:

LINUX

  • ArmPL 23.04.
  • OpenMP library provided by ARM.
  • Code is compiled with GCC.

MAC

  • ArmPL 23.06.
  • Vanilla LLVM OpenMP.
  • Code is compiled with vanilla LLVM Clang.

The crash typically occurs after running the application for some time. Note that I use a wrapper around ArmPL. On macOS, I get the following output:

C  [libomp.dylib+0x5750]  ___kmp_fast_free+0xf0

On Linux, I get this:

If I run without a wrapper, I get this:

The crash doesn't occur when using other BLAS/LAPACK implementations (OpenBLAS, vecLib). Any help with solving this problem will be much appreciated.
