Comment # 5 on bug 1060506 from Fabian Vogt

FWICT, the issue is the serialization in xerces-c, which dumps elements based
on the order in internal hash tables.

Those tables use a hash derived from the key pointers in some cases
("PtrHasher"), so the order can depend on the memory layout.

XTemplateSerializer.cpp has an define "XERCES_DEBUG_SORT_GRAMMAR" which if
enabled sorts the keys more deterministically (?). With that defined, xsdbin
emits consistent output here.

Oh, and there's also a bug that alignment space is not zeroed, but that's
actually deterministic, so not an issue in this context.
