Bug ID: 111538
Summary: Unhelpful message when returning initializer list when
deducing the return type
Product: gcc
Version: 13.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: barry.revzin at gmail dot com
Target Milestone: ---
Consider:
auto f(bool c) {
if (c) {
return 2;
} else {
return {};
}
}
This code is ill-formed, but the error gcc 13 gives is:
<source>:5:17: error: returning initializer list
5 | return {};
| ^
But returning an initializer list is fine... sometimes. It's just not fine
here, specifically. So would be nice if the error reflected that. Maybe
something to the effect of:
"error: returning an initializer list from a function with deduced return type
is not allowed"
