- Subject: [PATCH] fixheadercheck
- For some binaries we can get a invalid section alignment, for example if
- sh_align = 1 and sh_addralign is 0. In the case of a zero size section
- like
- ".note.GNU-stack", this is irrelavent as far as I can tell and we
- shouldn't
- error in this case.

- Upstream-Status: Pending
- Rebase to 0.170
