            Bug ID: 117853
           Summary: "warning: '?:' using integer constants in boolean
                    context, the expression will always evaluate to 'true'
                    [-Wint-in-bool-context]" but no ?: in sight
           Product: gcc
           Version: 14.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: nabijaczleweli at nabijaczleweli dot xyz
  Target Milestone: ---

With gcc (Debian 14.2.0-8) 14.2.0 I just got

/bin/bash ./libtool  --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. 
-DSYSCONFDIR=\"/etc\"   -DPKGDATADIR=\"/usr/share/ltrace\"

libltrace.c: In function 'signal_exit':
libltrace.c:83:21: warning: '?:' using integer constants in boolean context,
the expression will always evaluate to 'true' [-Wint-in-bool-context]
   83 |         exiting = 1 + !!os_ltrace_exiting_sighandler();
      |                   ~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

with bool exiting; and int os_ltrace_exiting_sighandler(void);

The warning is valid in principle (this /is/ always true), but there's no ?: in
sight. So the description should probably drop the ?: bit? Maybe?

The following repros this on current sid:

#include <stdbool.h>
bool exiting;
int os_ltrace_exiting_sighandler(void);
int main() {
        exiting = 1 + !!os_ltrace_exiting_sighandler();
}
