This test was invalid on modern glibc:
asprintf errors EOVERFLOW without attempting an allocation
when the size is at least INT_MAX - 32. INT_MAX - 33 is the
largest size that can attempt to trigger allocation failure,
and will not necessarily accomplish that on some systems.

Create a library that is specified to wrap malloc trivially,
to accomplish the goal of the test without external dependencies
or inconsistently implemented behavior.
