There is no problem.  POSIX explicitly says

3.3.1.3 [...]
(2) SIG_IGN -- ignore signal
    [...]
    (d) If a process sets the action for the SIGCHLD signal to SIG_IGN,
        the behaviour is unspecified.


Your program is not POSIX compliant if it sets SIGCHLD to this value
and therefore the library need not be either.
