&bytes[0]
on line 500 causes an assertion failure ifcount == 0
.On the main branch it will probably be better to fix this by using
bytes.data()
like the TODO comment suggests.I looked for variants by removing this clause from the CodeQL query. The other results look like false positives to me, but most of them should probably also be replaced by
bytes.data()
on main.
