Unsafe "index" function from delayed array

[niko...@gmail.com]

Hello,

I've came across a very nasty bug which has caused segfaults in my code. It appears that when you use "index" on delayed array, it will be unsafe:

ghci> let a = delay $ fromListUnboxed (ix2 16 16) [(1::Int)..16*16]
ghci> a ! (ix2 100 100)
139666186078901
ghci>

This was very unexpected, I've spent half a day trying to find a cause of a segfault. Please, fix this in future versions.

Nikolay.
