The LSAN library/functionality in clang can be incredibly helpful when finding
memory leaks [1].
As of right now the functionality isn't built with devel/llvm22. It's trimmed
out via cmake and/or the port Makefile (see `COMPILER_RT_IGNORELISTS` in
https://cgit.freebsd.org/ports/tree/devel/llvm22/Makefile?id=4d0a5a9f13c7eb4ac19057d4821e83c9665ec195
).
