This one, probably not: ignoring errors is still evil, and should be
discouraged / fixed. I would say it is rather a matter of making bugs
(unchecked calls) have less serious consequences: empty hashes instead of
NULL dereference. OTOH, I believe a NULL dereference is not exploitable and
is detectable immediately, which is good, while an empty hash is hiding the
bug, and may cause security concerns.

So I do not know if it is a good idea or not. It was just easy to write
while waiting on compilation.
