Comment:
The .ll file is too big to attach, but I've put it at
http://www.tiresiaspress.us/other/Char.ll
I haven't changed the iteratee source; I just tried building from a fresh
"cabal unpack".
I've double-check the ghc version (7.2.1 x64 and 7.2.2 x64), but is there
a good way to check the llvm version? I should only have 2.9 installed,
and e.g. llvm-ld --version shows
{{{
$ llvm-ld --version
Low Level Virtual Machine (http://llvm.org/):
llvm version 2.9
Optimized build.
Built Nov 15 2011 (03:37:10).
Host: x86_64-apple-darwin11
Host CPU: i686
Registered Targets:
(none)
}}}
Also, the panic only happens when building with profiling enabled.
