Bug ID: 88313
Summary: generic lambda in default template argument
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: blitzrakete at gmail dot com
Target Milestone: ---
gcc (with no flags) rejects the following code:
// 'auto' parameter not permitted in this context
template <int = [](auto) { return 0; }(1)>
void f();
This is bogus because anywhere where a non-generic lambda is allowed, a generic
one is allowed too. Replacing 'auto' with 'int' makes gcc accept the code.
