--- Comment #7 from Tom Tromey <tromey at sourceware dot org> ---
queue_and_load_all_dwo_tus can seemingly create new type units
even though it is called by dw2_do_instantiate_symtab - i.e.,
after the initial scan is done.
So probably this code should either reallocate the symtab
vector when doing this (may be expensive unless we can count
how many additions there will be); or maybe the assert
removed.
This is pretty surprising to me, though I guess I don't really
understand the DWO code.
