Insufficient location information for parse errors before ''module'' keyword
I've seen this error with GHC 6.6 on a PPC Mac (10.4.8), but I suspect it happens on multiple systems.
Consider Main.hs
module Main where
import Test
main = test
and Test.hs
mmmodule Test where
test = putStr "stutter"
The error message for trying to load the Main module is
$ ghci Main
[snip]
Loading package base ... linking ... done.
<no location info>: file name does not match module name `Main'
Failed, modules loaded: none.
Prelude>
This provides no information regarding the actual location of the error. In a program of a considerable number of modules, the offending module can be difficult to track down. Moreover, the error provides no direct indication that there's a source file without the module keyword in it.
The path of the offending file should be included in the error.
