Subject: Re: [Caml-list] Ouch - when bytecode and native behave differently
Date: Thu, 3 Oct 2002 10:11:05 +0200 (CEST) [thread overview]
Message-ID: <Pine.LNX.4.33.0210031007060.21678-100000@lcavpc19.epfl.ch> (raw)
In-Reply-To: <8765wkao05.fsf@foxthompson.net>
This is filed as bug 1347 in the ocaml 'bugzilla'
Another similar bug is that in bytecode, a divide-by-zero is reported as
"Fatal error: exception Division_by_zero", whereas in native you get
"Floating point exception".
