It's this assert that's failing:
...
1369 gcc_assert (flag_ltrans
1370 || (!node->in_other_partition
1371 && !node->used_from_other_partition));
...
because:
...
(gdb) p flag_ltrans
No symbol "flag_ltrans" in current context.
(gdb) p node->in_other_partition
$1 = 1
(gdb) p node->used_from_other_partition
$2 = 0
(gdb) p global_options.x_flag_ltrans
$3 = 0
...
for node:
...
(gdb) call debug_generic_expr (node.decl)
results
