8.5alpha3 bug in information_schema.table_privileges

pagila=# select * from information_schema.table_privileges;
TRAP: FailedAssertion("!(idx[0] < (((int *) (((char *) (acl)) +
sizeof(ArrayType)))[0]))", File: "acl.c", Line: 1740)
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.

On a build without assertions it dumps core, which gives a backtrace like so:

Both of those systems run Solaris, though one was compiled with gcc, the other
with SunStudio. I can probably dig up more info if needed.

Oh, seems it might be related to one of:
