Possible wrong code

[drhaozhong]

The code is as follows:

`struct attribute ((aligned (8))) S8 { char a[8]; };
struct attribute ((packed)) S1 { struct S8 s8; };

char a[_Alignof(struct S8)] = {0};
char b[_Alignof(struct S1)] = {0};`

This code is compiled into a size 8 array for a and size 1 array for b. Alignof is inconsistent, which i'd expect to be an error (or warning at least).

Here, gcc will warn the errors:

:4:17: error: expected primary-expression before 'struct' 4 | char a[_Alignof(struct S8)] = {0}; | ^~~~~~ :4:8: error: '_Alignof' was not declared in this scope 4 | char a[_Alignof(struct S8)] = {0}; | ^~~~~~~~ :5:17: error: expected primary-expression before 'struct' 5 | char b[_Alignof(struct S1)] = {0}; | ^~~~~~ :5:8: error: '_Alignof' was not declared in this scope 5 | char b[_Alignof(struct S1)] = {0}; | ^~~~~~~~ Compiler returned: 1
