We have
1235 /* Lambda functions in templates aren't instantiated normally, but
through
1236 tsubst_lambda_expr. */
1237 if (lambda_fn_in_template_p (tmpl))
1238 return NULL_TREE;
but since r266056 we allow lambdas in a template-parameter-list:
--- a/gcc/cp/semantics.c
+++ b/gcc/cp/semantics.c
@@ -2988,12 +2988,6 @@ begin_class_definition (tree t)

-}

/* According to the C++ ABI, decimal classes defined in ISO/IEC TR 24733
are passed the same as decimal scalar types. */
if (TREE_CODE (t) == RECORD_TYPE
Jason, should we also return NULL_TREE for lambdas inside template parameter
list (in retrieve_specialization)?

Note, there is another ICE, debug_tree (tmpl) ICEs on: #1 0x009aa1d1 in dump_template_decl (pp=0x2f5fde0 , t=, flags=128) at ../../gcc/cp/error.c:1396 1396 gcc_assert (TREE_CODE (TREE_TYPE (t)) == TEMPLATE_TEMPLATE_PARM); because TREE_TYPE (t) is a METHOD_TYPE rather than TEMPLATE_TEMPLATE_PARM.
