- Subject: dwarf2out suspicious code
I fell over this assert in dwarf2out.c, but the later comment says it
can happen?? does a checking build fail on LTO?
static inline void
add_AT_die_ref (dw_die_ref die, enum dwarf_attribute attr_kind,
gcc_checking_assert (targ_die != NULL);
/* With LTO we can end up trying to reference something we didn't create
a DIE for. Avoid crashing later on a NULL referenced DIE. */
if (targ_die == NULL)
