Technically this isn't allowed by the C spec, but it's been seen in the wild: see https://lgtm.com/projects/g/libcsp/libcsp/snapshot/3763c7b3380f95c81636de5c95156fd3ef151a21/files/src/csp_buffer.c\#x1d04047d2bb68c21:1

Since
voidis generally considered a 1-byte type when doing pointer arithmetic, these results are usually false positives.Technically this isn't allowed by the C spec, but it's been seen in the wild:
