            Bug ID: 34308
           Summary: p sizeof(bool) gets an error
           Product: gdb
           Version: HEAD
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdb

Created attachment 16790
  --> https://sourceware.org/bugzilla/attachment.cgi?id=16790&action=edit
C program to demonstrate issue

bool is a variable type in C23 but gdb is unaware of it.
attachment hello.c declares "b" as "bool":-
gcc -g3 -gdwarf-5 -o hello hello.c
16:50:24$ gdb hello
GNU gdb (GDB) 18.0.50.20260619-git
Reading symbols from hello...
(gdb) b main
Breakpoint 1 at 0x401135: file hello.c, line 7.
(gdb) run
Starting program: /dimstar/home/dunc/tests/hello 
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".

Breakpoint 1, main (argc=1, argv=0x7fffffffdca8) at hello.c:7
7         nc = write(1, "Hello world!\n", 13);
(gdb) p sizeof b
$1 = 1
(gdb) ptype b
type = _Bool
(gdb) p sizeof(_Bool)
$2 = 1
(gdb) p sizeof(bool)
❌ No symbol "bool" in current context.
