Bug ID: 99081
Summary: Misleading -Wmissing-field-initializers warning on
out-of-order designated initializers
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: rs2740 at gmail dot com
Target Milestone: ---
struct A {
int a; int b;
};
A a { .b = 1, .a = 2};
with g++ -std=c++2a -O3 -Wall -Wextra produces
<source>:5:21: warning: missing initializer for member 'A::a'
[-Wmissing-field-initializers]
5 | A a { .b = 1, .a = 2};
| ^
<source>:5:21: error: designator order for field 'A::a' does not match
declaration order in 'A'
The real problem is the error, of course, but the warning is just noise and
also incorrect - there is an initializer for a in the code, after all.
