<!-- Enable hardware memory tagging (ARM MTE) in this process.
When enabled, heap memory bugs like use-after-free and buffer overlow
are detected and result in an immediate ("sync" mode) or delayed ("async"
mode) crash instead of a silent memory corruption. Sync mode, while slower,
provides enhanced bug reports including stack traces at the time of allocation
and deallocation of memory, similar to AddressSanitizer.
See the <a href="https://community.arm.com/developer/ip-products/processors/b/processors-ip-blog/posts/enhancing-memory-safety">ARM announcement</a>
for more details.
