commit r14-12449-g49b60a20de51bd0a0b0ba745f2f1ccf2e5970dfb Author: Richard Biener <[email protected]> Date: Fri Jan 30 14:55:58 2026 +0100 debug/123886 - remove GTY((skip)) from external_die_map entry The following avoids GCing IDENTIFIER_POINTERs referenced from external_die_map after we clear ggc_protect_identifiers. I never expected those to be GCed. PR debug/123886 * dwarf2out.cc (sym_off_pair::sym): Remove GTY((skip)).
