Bug ID: 109526
Summary: Broken type name for anonymous struct containing a VLA
member in diagnostic message
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: xry111 at gcc dot gnu.org
Target Milestone: ---
void test(__SIZE_TYPE__ len, char *x)
{
struct
{
char data[len];
} *p = x;
}
The diagnostic message is:
<source>: In function 'test':
<source>:6:12: warning: initialization of '<U87b8> *' from incompatible pointer
type 'char *' [-Wincompatible-pointer-types]
6 | } *p = x;
| ^
"<U87b8>" does not make any sense to me.

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
If it was not a VLA type inside the struct we get:
<source>:7:12: warning: initialization of 'struct <anonymous> *' from
incompatible pointer type 'char *' [-Wincompatible-pointer-types]
7 | } *p = x;
| ^
Which seems better.
