[Bug c++/44263] New: missing diagnostic on questionable array sizes with -pedantic

[ebotcazou at gcc dot gnu dot org]

The C++ compiler now accepts the following constructs (parse/array-size2.C):

struct S
{
  char a[4];
  int b;
};

extern void bar (char *, char *);

void
foo (void)
{
  char g[(char *) &((struct S *) 0)->b - (char *) 0];
  char h[(__SIZE_TYPE__) &((struct S *) 8)->b];
  bar (g, h);
}

like the C compiler.  But it should warn on them in pedantic mode.
