current CVS crashes in find_basic_blocks during bootstrap

[Jan Hubicka]

Zack,
I've noticed same crash from time to time when bootstrapping on K6.  What
always helped me whas clean rebuild so I've assumed that problem is somewhere
in Makefile dependencies.  Perhaps make clean will help for you too, on the
other hand this problem ought to be investigated, I will try to do so once I
get it next time.  And (at least for me) this problem exists few months now and
is --enable-checking specific.
