Am 23.09.22 um 12:09 schrieb Martin Kaiser:
This function compiles
void dummy123(void)
{
{ enum { BLA = 2 }; };
{ enum { BLA = 2 }; };
}
but this one doesn't:
void dummy123(void)
{
{ enum { BLA = 2 }; };
volatile int a = 3;
{ enum { BLA = 2 }; };
}
That these two are handled differently looks like a bug to me; I suggest
to file a bug report.
BTW: The whole point of this exercise is to use a compile-time assert macro
such as
#define ct_assert(e) { enum { ct_assert_value = 1/(!!(e)) }; }
and allow this to be used before and after variable declarations.
Why not just use static_assert?
