2.1.1 Use and Implementation of Functions

  1. If an argument to a function has an invalid value (such as a value
outside the domain of the function, or a pointer outside the address
space of the program, or a null pointer), the behavior is undefined.


The spec never omits checking the validity of pointers unless actually
specified.  In this way, musl is definitely conformant.

There are some non-conformant bits of musl, though some of these may be
solved since the last test (which was musl 1.1.19):
