import gcc.builtins;
char *foo(char *buffer)
{
return __builtin_strcat (&buffer[0], "Li");
}
---
$ gdc test.d -Werror
test.d: In function ‘foo’:
test.d:5:3: error: ‘__builtin_memcpy’ reading 3 bytes from a region of size 2
[-Werror=stringop-overflow=]
return __builtin_strcat (&buffer[0], "Li");
^
cc1d: all warnings being treated as errors
---
This happens because although "Li" is a null terminated string, we give it the
type char[2]*.
