The intent was that unnamed temporaries should not be 'promoted' to coroutine frame entries. However there was a thinko and these were not actually ever added to the bind expressions being generated for the expanded awaits. This meant that they were showing in the global namspace, leading to an empty DECL_CONTEXT and the ICE reported. Signed-off-by: Iain Sandoe <i...@sandoe.co.uk> PR c++/105287 gcc/cp/ChangeLog: * coroutines.cc (maybe_promote_temps): Ensure generated temporaries are added to the bind expr. (add_var_to_bind): Fix local var naming to use portable punctuation. (register_local_var_uses): Do not add synthetic names to unnamed temporaries. gcc/testsuite/ChangeLog: * g++.dg/coroutines/pr105287.C: New test.
