Thanks for testing, I pushed a variant of the fix as:

libelf: Optimize elf_strptr.c validate_str by checking last char first
In most cases the last char of the sectio will be zero. Check that
first before calling memrchr. This is a minor optimization in normal
cases. But it helps asan a lot by removing the memrchr call in most
cases.
