Bug ID: 27567
Summary: Linking PE files adds alignment section flags to
executables
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld

patch to avoid section alignment flags for executables
Under wine, there is currently a problem where certain DRM systems will fail if
the wrong section characteristics on DLLs are detected.
Currently, ld will always add IMAGE_SCN_ALIGN_* characteristics for sections,
which does not match MSVC's output, therefore tripping the DRM.
According to
https://docs.microsoft.com/en-us/windows/win32/debug/pe-format#section-flags,
IMAGE_SCN_ALIGN_* is only valid for object files (as opposed to
image/executable files).
I have attached a patch that fixes this issue on my end by only applying
section alignment flags to object files (!(flags & EXEC_P)).
Thanks to Paul Gofman for providing the DRM research.
