Compiling lx (the lexical analyser generator) with -O, everything goes
smoothly until we get to the main file Lx.hs, on which ghc-3.02 panics
and dies. The (long!) -v output is included below. If I compile without
-O, everything is fine.
I don't include the lx source, because I think that's
Hi all,
When I 'make all' the current source tree, I get the following bus
error:
==fptools== make all --no-print-directory -r;

Hi,
thanks - looks

There is one aspect of Java that is relevant here:
A Java implementation is free to load and link classes in any order,
strictly or lazily, but it MUST report exceptions as if it had loaded

Infinities are probably best treated as a seperate issue.
That is, infinities should not correspond to exceptions.
If you have a type which supports infinities, then 1/0 should return
infinity, not raise an exception. Conversely, if you want 1/0
Fergus Henderson [EMAIL PROTECTED] points out that our exception handling
scheme hits problems if you hit an infinite loop instead of an exception.
Yes, this is a problem - and not a pretty one.
Fixes:
1) Remove fixpoints so that infinite loops don't happen.
Ok, so this isn't really an
Laziness appears to have a wierd interaction with IO.
According to the docs, you should add two numbers from the user like this:
main = do
hSetBuffering stdout NoBuffering
putStr "Enter an integer: "
x1 - readNum
putStr "Enter

Here's a reasonable design for exceptions in Haskell:
* handle :: (String - IO a) - IO a - IO a
You probably realized more quickly than I how this
can leak exceptions. What I mean is
main = do quotient - handle (const (return 0)) (return (0 / 0)
