Gentlemen,
ghc -v was not required, as I am building this using .hc files from
another host. Adding "-fno-builtin" to the CC opts did resolve the
problem. Furthermore, I believe I have confirmed that strlen is the
problem by succesfully compiling the library using "-fno-builtin-
strlen" instead of "-fno-builtin".
Thank you,

I'm pretty sure this is to do with calls to strlen() from
Data.ByteString.
Can you check for sure that gcc is being passed -fno-builtin? (use
ghc -v).
Failing that, we might have to use a private version of strlen()
that gcc doesn't try to inline.
Cheers,
Simon

As of 6.5.20050610 this still occurs on both the intel mac and
intel linux (Gcc 4.0.1 & gcc 4.0.2 respectively). Setting -fno-
inline for gcc has no effect.

Often I find these are the result of gcc inlining something, or
using its built-in primitives. We already pass -fno-builtin to
gcc on x86. Don - are there any C functions being inlined in
ByteString? If so, it might be a good idea to turn off the
inlining.
Cheers,

There's been a few changes since then, perhaps try again with last

Hmm! Very interesting. Register spill classes, eh? SimonM?

I am insufficiently experienced with the build process to
know if this was from an error in creating the .hc file or a
problem with the source. I have noticed that the file
ByteString.hs seems to be new.
I am building the .hc files on 386 linux (Ubuntu breezy
badger):
linux kernel 2.6.12
ghc-6.5.20060502 is installed
gcc is 4.0.2
I am using the registerised .hc files to bootstrap to Max OS
X x86
Mac OS X 10.4.6
no ghc installed
gcc is 4.0.1 (as included in Xcode)
