Bug ID: 93710
Summary: poor location in diagnostics of messages about array
initializers
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org
Target Milestone: ---
With one exception, the warnings for the invalid array initializers are not
associated with their location: they all point to the closing brace of the
initializer-list. When the list consists of many elements that can make it
quite difficult to understand which among them is causing the problem.
$ cat u.C && gcc -S -Wall -Wextra -Wpedantic u.C
struct A { A (int); A (char*); int i; };
int x;
A a1[] = {
0L,
&x, // accurate location
sizeof (A),
__builtin_offsetof (A, i)
};
