I seem to have found the ghc/gcc 2.95 problem. There was a bug in one of
the constraints on an inline-assembly fragment in the PrimOp for small
integer multiplication; patch below.
I've run some benchmarks, and gcc 2.95 does a *much* better job than 2.7.2.1
of compiling the garbage collector: i

I've tracked this down as far as PrelNum.hs in

If this helps (applies to linux-2.2.10, glibc-2.1.1, libgpm-2.0.2, compiled as
shared libs, AMD K6-II):
- As I've already said, using a egcs-1.1.2 compiled ghc-4.04 seems to work
fine, even with gcc-2.95 used as the C compile

I'm building i
I think, the only thing we can do is wait for GHC developers support of gcc2.95.

Unhappily, having managed to build hsc from scratch with gcc2.95 on Sparc/Solaris,
I can confirm that I still get a segmentation fault when I run it. So it looks like
we are stuck with gcc2.7.2. Is there anything that can be done about this?
Hmmm. On my machine, at least my own programs compile fine with ghc-4.04 and
gcc-2.95. I didn't yet try to recompile ghc-4.04, however.
FYI: it's a K6-II running linux-2.2.10 with glibc-2.1.1.

I haven't got around to testing it yet, but I'll let you know as soon as I
do.

Do these two work together? (I believe gcc2.95 is supposed to be descended
from egcs, which is supposed to sort-of-work with GHC).
