I am seeing this too. I tracked it back to line 5613 of
tree-ssa-loop-ivopts.c (rewrite_use_compare). There is
a line:
bound = cp->value;
and cp is null. cp is set with a call to get_use_iv_cost and that
routine does return NULL in some cases so I think we need to check
for a NULL cp before dereferencing it. I changed
if (bound)
to
if (cp && cp->value)
and set bound inside the if but now I am dying when compiling
decNumber.c so I don't have a bootstrap working yet.
