Subject: [Caml-list] Invalid_argument("equal: abstract value")?
Date: Wed, 31 Dec 2003 15:55:47 -0600 [thread overview]
Message-ID: <200312311555.47555.tom@launchbird.com> (raw)
I haven't seen this error before. Can someone provide an explanation?
I've traced the problem down to a structural comparison (=) between
two large data structures. I know functional comparisons are a
no-no, but what is an "abstract value"?
The problem occurred when I added big integers (Big_int.big_int) to
the data structures under comparison. Suspecting big ints can't be
structurally compared, I tried the following, but the compiler
printed "false" as I would normally expect:
let a = Big_int.zero_big_int = Big_int.unit_big_int in
if a then print_string "true\n" else print_string "false\n";
Regards,
Tom
