I'll try to track this down further as time permits. Thanks for the
report.
Replying to myself...
Jim, I believe i have tracked it down, so could you do some
experiments for me?
In my case I have found that the GCSE pass mis-optimizes the code in
unexelf.c When I recompile it with "-O2 -fno-gcse" I get a properly
functioning emacs build.
Could you try to recompile unexelf.o without any optimizations, and
see if this allows the resulting emacs to work just fine?
Using this, I can determine whether we are seeing the same bug.
Later,
David S. Miller
