New description:
'''See the reply from Simon''' which gives a simple stand-alone repro case
for this bug. Also fix #1754 first; may be the same thing.
Original report: To reproduce this bug please install GHC 6.8.20070916 and
Gtk2Hs 0.9.12 as currently described on
http://haskell.org/haskellwiki/Grapefruit#Building. There is a modified
version of the development version of Grapefruit attached. Sorry for this
large code example but currently I really don’t have the time to reduce
this any further.
Please unpack the attached file {{{bug.tar.bz2}}}, enter the directory
{{{bug/Haskell}}} and run {{{ghci -cpp -farrows -fth -fglasgow-exts
Examples/Simple.hs}}}. Compilation to bytecode should be successful.
Then enter {{{main}}} on the GHCi command line. You should get the
following messages:
{{{
ghc-6.8.0.20070916: panic! (the 'impossible' happened)
(GHC version 6.8.0.20070916 for i386-unknown-linux):
nameModule arr{v a85X}
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
}}}
