Bug ID: 118308
Summary: compiling code that should return without a return
statement
Product: gcc
Version: 14.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: raffaellobertini at gmail dot com
Target Milestone: ---
This following code is compiling:
file test.c
```
#include <stdbool.h>
#include <stdio.h>
bool f()
{
printf("f");
}
int main(int argc, char* argv[])
{
f();
return 0;
}
```
but what f() returns? I experienced a similar code that in win-mingw returning
true and in linux returning false.
compiling just with defaults gives no error: `gcc test.c`
In my perspective should not compile at all as it does not return a value
explicitly.
To have that kind of error it must be compiled with '-Werror-return-type'
Would it be possible to enable by default the -Wreturn-type at least?
and if someone doesn't want it will compile with 'Wno-return-type' ?
