Bug ID: 106584
Summary: g++ not showing correct line number in "use of deleted
function" error
Product: gcc
Version: 12.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: accelerator0099 at gmail dot com
Target Milestone: ---
Example code:
----------------------------------------------------
#include <map>
#include <memory>
using int_map = std::map<int, std::unique_ptr<int>>;
void f(int_map cl);
void f2() {
int_map cl;
f(cl);
}
----------------------------------------------------
The actual error is that int_map is not copiable, so line 10 is ill-formed
But the compiler doesn't tell you anything about line 10, it just prints tons
of waste
This is unreasonable. You may make such a careless mistake (missing a '&') in
thousands of lines, the compiler should locate where the error is for you.

At least it tells you about where the error is, otherwise you may fall into thousands of lines of source code without knowing where to edit ^ permalink raw reply [flat|nested] 6+ messages in thread
