New description:
In GHCI execute
{{{
let powers = 2:map (2^) powers
powers
}}}
When calculating the fourth element of the list, you get the following
error message:
{{{
<interactive>: internal error: getMBlock: mmap: Invalid argument
(GHC version 6.12.1 for i386_unknown_linux)
Please report this as a GHC bug:
http://www.haskell.org/ghc/reportabug
}}}
If you have trouble reproducing the bug, try substituting an other number
for 2 in the code, e.g. I have also got that error message when I defined
powers as:
{{{
let powers = 4:map (4^) powers
}}}
and
{{{
let powers = 13:map (13^) powers
}}}
