Bug ID: 48910
Summary: Wrong size of struct with aligned bitfield (Linux)
Product: clang
Version: 11.0
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C
Assignee: unassignedclangb...@nondot.org
Reporter: ju.o...@gmail.com
CC: blitzrak...@gmail.com, dgre...@apple.com,

Consider
typedef char __attribute__((aligned(2))) Char;
struct X {
Char c:1;
Char d:1;
};
int g(void) {
return sizeof(struct X);
}
gcc returns 4, clang returns 2 on the x86_64-unknown-linux-gnu target.
