Bug ID: 108069
Summary: Cant expand multiple parameters packs when used with a
concept prefix when used inside a variadic templated
lambda
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: calebxyz at gmail dot com
Target Milestone: ---
When using concepts in a variadic templated lambda, G++ cannot expand a concept
prefix leading to misleading errors, while almost the same code without
concepts works fine.
Clang compiles the concept code without any errors.
Link to both examples of code
get_nth1 - uses concepts and doesn't work.
get_nth2 - uses void* and compiles fine
