struct tree_common { enum tree_code code : 8; }; This used to work correctly in 2.95.3
Forgot to say this is the ICE I get on the mainline: test5.c:3: error: use of enum `tree_code' without previous declaration test5.c:3: error: field `code' has incomplete type test5.c:2: internal compiler error: tree check: expected class 't', have 'x' (error_mark) in layout_class_type, at cp/class.c:4626 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions.

It could just ignore "code" after issuing the error. -- Gaby
Confirmed. We started ICEing in in or before 3.2.3, but it worked in 2.95. W.
