Bug ID: 122072
Summary: bad diagnostic for non-local lambda with a
simple-capture
Product: gcc
Version: 15.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ing.russomauro at gmail dot com
Target Milestone: ---
The following code, compiled with C++11 or C++23 with gcc 15.2 :
( https://godbolt.org/z/W6374PbYn )
int x;
auto f = [x]{};
int main(){}
badly provides priority to the warning related to capturing a non-automatic
variable, instead of the fact that a non-local lambda cannot have
capture-default or simple-captures.
For example:
auto g = [=]{};
well triggers the expected error.
Really, as far as I know, even the warning above should be an error.
