Hi all,
When running ASAN on an internal library that utilizes ARMPL's FFT functionality, the following issue was reported. Here's the relevant portion of the ASAN trace

System info: Ubuntu 22.04, aarch-64, Linux kernel v6.8.0-83-generic
Tested on ARMPL versions: 24.10. 25.04, 25.07, 25.07.1
I couldn't find this reported before. Has anyone seen this? Let me know if you need more information.
Thanks,
Andrew
