Bug reports on LibO 5 x86 or x64-64 version on 64-bit Windows

Hi,

Is there any simple, boilerplate way in bugzilla for reporters to tell
whether the observed behavior of LibO 5 on 64-bit Windows is actually
about x86 or x86-64 version (or both)?
Current combination of fields "Version"/"Hardware"/"OS" does not suffice
for the purpose.

For example, the reporter of [1] said that the crash happens with x86-64
version but not with x86 one on 64-bit Windows [2].
So I suppose that it is due to loading 32-bit TWAIN library, and that
it would be helpful to clarify which one of the two version is described
in some other issues on 64-bit Windows.
