--- Comment #8 from Xi Ruoyao <xry111 at gcc dot gnu.org> ---
#pragma pack(push)
#pragma pack(1)
struct S0 {
signed f0 : 22;
uint32_t f1;
unsigned f2 : 5;
unsigned f3 : 21;
unsigned f4 : 8;
signed f5 : 22;
signed f6 : 1;
signed f7 : 23;
signed f8 : 10;
};
#pragma pack(pop)
Removing these #pragma silence the UBSan. But I bet the code is just invalid
with those #pragma and with #pragma removed the issue will just gone, like
PR109982.
