Bug ID: 90647
Summary: Warn on returning a lambda with captured local
variables
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: antoshkka at gmail dot com
Target Milestone: ---
Consider the example:
auto test(int s) {
return [&s] { return s; };
}
`s` is a local variable, so we return a lambda that has a dangling reference.
It would be nice to have a warning for such cases.
