Mike, I've tried to get a successful bootstrap with your patches (on
i686-pc-linux-gnu) but failed:  The stage1 compiler hangs while
compiling regclass.c (compiling options -O2 -g).

Although I do not agree with your "solution" to the null JUMP_LABEL
field in the routine loop_iterations in unroll.c, you might be able to
give "the rest of us" useful information because your build completes.

What I would like you to do is to send me the uuencoded, gzip'd tar file
of the following:

A compilation of your test program [that originally blew up due to
JUMP_LABEL being zero], using *your* compiler, with the following flags:

-O2 -g -da

This will enable me to see which pass mangles the JUMP_LABEL, which
might make searching for the culprit somewhat simpler.

Thanks in advance,
