Title: RE: fatal error; There might be a bug in the compiler
I have searched high and low for the cause of the error. There are no cases where a value depends on itself, so I suspect a compiler problem, or something in the evaluation that is more subtle. I have put the whole set of code below.
Title: RE: fatal error
When I
took this function by it self, it seemed to not cause the fatal error. It only
fails in the context that I use it in. I will have to do some more
experiments.
Sorry
to waste your time on this message.

Title: RE: fatal error
Keith,
I think you are right about the black hole, but I don't see how my code causes it. I have put the offending function below for you to see. If I remove the recursive calls to polyR, I do not get the deadlock.

I have solved the problem!
I had -syslib posix in my options but it has been before -syslib util.
When I put at after this option, evrything links fine.
So that seems to be a problem of order.

I think I like the idea, but if we do this, do we lose the ability to
pattern-match strings? Or should we consider an automatic (or explicit)
conversion to [Char] when needed? Or some way to provide functions
(like snull, shead, stail) that w

Yes I fear some of the conversion functions will have to call error in
certain situations, which is not ideal. For exampl

When GHC goes to Unicode, things will get complicated. Packed

It was

trace. Does anyone know any other causes?

a lot of infinite lists. Could there be some kind of evaluatio

I made a few changes to a program and now get:
main: fatal error: No threads to run! Deadlock?
Can someone shed some light on the general conditions that cause this so I can debug it?

It would probably speed up my code somewhat if the GHC libraries provided
more support for PackedStrings. For example, some code I have
reads in stuff from a Posix fd (using Posix.fdRead) and then feeds it
to the GHC regular expression interface (using RegexString.matchRegex).
It is frustrating t
