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.
