[EMAIL PROTECTED] reports the following problem.
Version: 1.4 Beta (Version 971106)
OS: SGI Irix 6.3
compiler: SGI cc compiler version 7.3
configuration: CC=cc CFLAGS=-O2
Expected behaviour:
given David Elsworthy's test file
f :: Int -> String
f x = show (x,x,x)
g = 1.0 :: Int
load this into hugs, at the error message comment out g in editor and reload
this succeeds, now evaluate f 1
result: "(1,1,1)"
Observed behaviour:
evaluating f 1 gives a program error: {.... followed by an internal error
