Known bug.
I tried to follow the code in parse_btype() in tccgen.c for the missing
struct member symbol lookup check, but didn't succeed so far:
} else {
c = 0;
flexible = 0;
while (tok != '}') {
if (!parse_btype(&btype, &ad1)) {
skip(';');
continue;
}
Member lookup is linear, so checking for duplicates is quadratic, so TCC
doesn't bother to do it. The check would belong to struct_decl, not
parse_btype, probably involving find_field before adding it.
Ciao,
Michael.
