--- Comment #6 from Alexander Grund <alexander.gr...@tu-dresden.de> ---
Oh and for completeness: The same applies to the following union, doesn't it?
I.e. given this:
struct TF_TString_Raw {
uint8_t raw[24];
};
struct TF_TString_Small {
uint8_t size;
char str[23];
};
struct TF_TString_Large {
size_t size;
size_t cap;
char *ptr;
};
union{
TF_TString_Raw raw;
TF_TString_Small smll;
TF_TString_Large large;
} x;
it is not allowed to access x.raw.raw[0] AND then x.large.size (not even a
common initial subsequence) but also not x.raw.raw[0] AND then x.small.size
(maybe a common sequence, not sure about the array, but not implemented in GCC)
