5 | |||
6 | For some binaries we can get a invalid section alignment, for example if | ||
7 | sh_align = 1 and sh_addralign is 0. In the case of a zero size section | ||
8 | like | ||
9 | ".note.GNU-stack", this is irrelavent as far as I can tell and we | ||
10 | shouldn't | ||
11 | error in this case. | ||
