Bug ID: 103236
Summary: ICE: in tsubst_pack_expansion, at cp/pt.c:13162
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: hewillk at gmail dot com
Target Milestone: ---
This seems to be an old bug, but I haven't found the dup of which bug it is.
Maybe I have reported a similar one a long time ago, but I'm not sure.
template <class... Ts>
void foo(const Ts&...) {
([] {
[](auto) { }([](auto... x) { x; });
}(), ...);
}
int main() {
foo(0);
}
