Maybe.  Or maybe $SIG{CHLD} = 'IGNORE' doesn't work.  It looks like a
lot of this discussion has been had before with bug #18849.  Is it
possible that the problem you are running into currently is related to
this bug and Perl is not doing the right thing wrt SA_NOCLDWAIT on your
failing platforms?

What behaviour do you get now with your C code in the bug db?
