I'm not sure if DECL_USER_ALIGN || DECL_P is the right test for this, I'd say
instead
if (DECL_SECTION_NAME (decl) != NULL_TREE
&& !DECL_HAS_IMPLICIT_SECTION_NAME_P (decl))
is what is the problem here, this is what I'm using in asan.c to find out
whether it is ok to increase alignment and/or add padding after the decl.
It is a common way of filling arrays to just put variables into user defined
sections, and expect the whole section to contain an array of those decls. Any
alignment increases there or additional paddings of course break that
assumption.
