Add a more meaningful case.
$cat p.cc
void a() {
auto var = [] (auto, volatile b) {};
}
$g++ p.cc
p.cc: In function ‘void a()’:
p.cc:2:35: error: ‘b’ does not name a type
2 | auto var = [] (auto, volatile b) {};
| ^
p.cc:2:40: error: expected ‘)’ before ‘;’ token
2 | auto var = [] (auto, volatile b) {};
| ~ ^
| )
p.cc:2:40: internal compiler error: in dependent_type_p, at cp/pt.c:26326
0x6c0f63 dependent_type_p(tree_node*)
../../gcc/cp/pt.c:26326
While in Clang
$clang++ p.cc
p.cc:2:35: error: unknown type name 'b'
auto var = [] (auto, volatile b) {};
^
1 error generated.
Noted that why GCC emits "expected ‘)’ before ‘;’ token" and has an ICE on the
";"?
Also, this situation may happen in the real world when someone just leaves a
type specifier out by a mistake.
