Bug ID: 110855 Summary: std::source_location doesn't work with C++20 coroutine Product: gcc Version: 14.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: hewillk at gmail dot com Target Milestone: --- When I try to use source_location to debug C++ coroutine: auto initial_suspend(const std::source_location location = std::source_location::current()) { return std::suspend_never{}; } I found that gcc does not allow this with: cc1plus: error: taking address of an immediate function 'static consteval std::source_location std::source_location::current(__builtin_ret_type)' In function 'void bar(bar()::_Z3barv.Frame*)': Not too sure if this is a valid code, although other compilers compile fine. https://godbolt.org/z/qddrsvsT9
