In case it is a binutils problem, I've attached a '.a' file sufficient to fully
link the program. To get to the problem jump is pretty easy:
gdb ./mlyacc.bad
break Chunk6
run

hold-down enter

do so. Can someone update this to New?

Actually, the prefetching is for the following loop:
for (i = 0; i p[2]; i++)
q[i] = 0;
I do not understand why unrolling of this loop affects other part of
the program that has longjmp.
