I disagree strongly. If the OP's system suffers a kernel panic, it's a
kernel problem which *needs* to be fixed. Otherwise the system is open to a
trivial denial-of-service attack: any userland program can replicate
whatever any library does to trigger the panic.

If upgrading the libraries did make the problem go away (which I doubt in
this case), then the OP might have a working system, but the stability of
FreeBSD as a whole would be the worse for it.

Brian.
