I disagree. The C standard (and also Posix) have clear rules about
application namespace, and sanitizers have to obey them or are broken.

I very well understand your POV here, but it is important to fully understand
the problem before changing random things. It may be a simple bug in the
sanitizers build system that this specific instance links statically, while
it is supposed to linke dynamically (with ELF symbol overriding semantics).
