Possibly.  In the general case (as specified by standards), what
happens to SIGCHLD if it was set to SIG_IGN before exec() is
ill-defined.  Some systems will inherit the SIG_IGN setting, which
will then cause any executed program that depends on wait() working
(e.g., shells) to fail.

The new POSIX draft, at least, sanctions the automatic reset of
SIGCHLD to SIG_DFL upon exec().
