c416c52bcdb120db5e8c53a51bd78c4360daf79b c++ ICE with nested requirement as default tpl parm[PR94827]
Template headers are not incrementally updated as we parse its parameters.
We maintain a dummy level until the closing > when we replace the dummy with
a real parameter set. requires processing was expecting a properly populated
arg_vec in current_template_parms, and then creates a self-mapping of parameters
from that. But we don't need to do that, just teach map_arguments to look at
TREE_VALUE when args is NULL.
* constraint.cc (map_arguments): If ARGS is null, it's a
self-mapping of parms.
(finish_nested_requirement): Do not pass argified
current_template_parms to normalization.
(tsubst_nested_requirement): Don't assert no template parms.
