Description
The C_i_integerp function doesn't first unpack flonum values before checking if they represent infinity or NaN. On x86-64, this means that (integer? +nan.0) => #t and (integer? +inf.0) => #t.
A suggested initial patch is at http://paste.call-cc.org/paste?id=2d5b17c595ae79bacbe36c52d4613ccd3e0373a2, but Christian said he'd work on a proper patch which includes changes to the testsuite to catch these errors (for the other number predicates too).
