Only if one registers a custom allocation function whose behavior violates
the documented [1] requirement to terminate the program on failure.

    No error return is allowed from any of these functions, if they
    return then they must have performed the specified operation.
    In particular note that allocate_function or reallocate_function
    mustn’t return NULL.
