Ouch, how embarrasing - I looked for that place,
but apparently failed to notice it. Sorry.

Anyhow, I checked it out as described (in a clean directory), recompiled
and ... the problem is still there. More strange, it also fails to work with
the "simple" regalloc.

I will submit a bug, but first I must figure out how to use the bugpoint
utility.

Just to rule out one case of confusion:
1) I build the tools with no options, except for pointing out to
   configure, where the llvmgcc is.
2) I try to enable linear scan register allocation by supplying
    "-regalloc=linearscan" to "lli" - no other options are needed, right ?

The code triggering the bug is the "lame" benchmark in the "mibench"
benchmark suite, by the way.
