A bug in something as basic as malloc/free thread handling would
start causing ported C programs to fail almost immediately. The
operating system code would never get out of testing in such a state
let alone be released to users. malloc is called far too often.

I would not be shocked if some rare latent bugs existed in the average
threaded libc, after all, bugs are common in software, and
multithreading is particularly hard.

However, I would be shocked if a single threaded libc did not handle
this particular case in as bug free a manner as the rest of malloc
itself. If one is willing to accept the use of the system malloc in
the non-threaded case on the premise that it is reasonably bug free,
then one should likely accept that it handles thread safety as well.
