--- Comment #17 from Rafał Mużyło galtgendo@o2.pl --- ...also, I've said 'plain OOM *or* VMS';
In that uxtheme bug, uxtheme is only loaded for the crash dialog, so at that point it could be either. It actually doesn't matter; what does is that being unable to load library due to lack of memory (in one sense or the other) is far more likely than the library that has very little code (and seemingly no conditionals) not getting built.
