Bug ID: 101232
Summary: Bad error message with stray semicolon in initializer
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: tobi at gcc dot gnu.org
Target Milestone: ---
This example (Link to compiler explorer: -> https://godbolt.org/z/rxsreYs8Y
<-):
=========================
struct X {
int a;
int b;
};
void f() {
auto x = X{ 1, 2; };
}
========================
Gives the fairly misleading error message
<source>: In function 'void f()':
<source>:7:15: error: expected primary-expression before '{' token
7 | auto x = X{ 1, 2; };
| ^
The error message is of the same kind all the way from GCC 4.1.2 up to the
current trunk.
For comparison, clang gives the much more helpful
<source>:7:21: error: unexpected ';' before '}'
auto x = X{ 1, 2; };
^
