Subject: Overflow causes crash in Int32 division
Date: Wed, 03 May 2006 18:37:07 -0700 [thread overview]
Message-ID: <44595AC3.5060400@coverity.com> (raw)
I've noticed that the following causes a crash on both the bytecode
interpreter and native code:
open Int32
open Printf
let _ = printf "%ld\n" (Int32.div Int32.min_int (-1l))
This doesn't appear to be documented, so I presume it's incorrect
behavior. Nativeint also seems to have the same problem. The built-in
int type doesn't seem to have the same problem. Int64 doesn't seem to
have a problem either.
This is on a 32-bit Windows platform.
