STEPS TO REPRODUCE
1. Create the file "Panic.hs" with the contents:
{{{
module Main where
main = print 1
}}}
2. Compile with "ghc -fext-core Panic.hs"
EXPECTED BEHAVIOR
Generation of the Core file "Panic.hcr".
ACTUAL BEHAVIOR
{{{
$ ghc -fext-core Panic.hs
[1 of 1] Compiling Main ( Panic.hs, Panic.o )
ghc: panic! (the 'impossible' happened)

As it states, I am using GHC version 7.4.1 for x86_64 Linux, on an x86-64
Linux box running Ubuntu 11.10 an Linux kernel 3.0.0-14-generic.
