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.
