In our case, the compile bug is called from function update_dep. Variable
was_spec is true, dep_spec_p (dep) is false, current_sched_info->flags &
DO_SPECULATION is zero, DEP_STATUS (dep) & SPECULATIVE is zero. So in this
case, we should avoid to free the memory of spec_dependency_cache.
1191 if (was_spec && !dep_spec_p (dep))
1192 /* The old dep was speculative, but now it isn't. */
1193 change_spec_dep_to_hard (sd_it);
1194
(gdb) p was_spec
$11 = true
(gdb) p dep_spec_p (dep)
$12 = false
(gdb) p current_sched_info->flags & DO_SPECULATION
$13 = 0
(gdb) p DEP_STATUS (dep) & SPECULATIVE
$14 = 0
(gdb) p !dep_spec_p (dep)
$15 = true
