Comment(by benl):
The mangler also fails with GCC 4.1.2 on {{{integer-gmp/cbits/gmp-
wrappers.cmm}}}, probably because it's hand written cmm code and not
produced by GHC proper.
At this point in time, we have a working GHC 6.10.1 binary distro, with a
broken {{{-fasm}}} and the head with a broken {{{-fvia-c}}}. Bootstrapping
the head with 6.10.1 requires the following carefully staged build
options:
{{{
SRC_HC_OPTS = -O0 -fvia-c -H64m
GhcStage1HcOpts = -O
GhcStage2HcOpts = -O0 -fasm
GhcHcOpts = -Rghc-timing
GhcLibHcOpts = -O0 -fasm -XGenerics
}}}
