Like Pavel, I can't see anything wrong with that code --- it's not quite
according to PG project style, but it certainly looks like it does what
it needs to. I think he's right to suspect some inconsistency in your
coding environment. One concrete idea worth considering is that maybe
you are compiling with headers that postdate commit 3f8c8e3c6 et al and
trying to use the code in a database that predates that. That'd result
in successfully compiling a call to a nonexistent core function, which
might end up as a crash depending on what your dynamic linker does
about it.
What exactly does the crash look like --- anything interesting in the
postmaster log? (If your logging setup fails to capture postmaster
stderr, now would be a good time to fix that.) Have you tried to
get a back-trace with gdb?

PS: for reference, this is the patch I'm wondering about:
