Looking at the final file looks like that code segments are not
set correctly.
In particular before this method there is a
#pragma code_seg(pop)
line that reverts the segment to the default one which is non-paged
while this method is supposed to be paged.
Maybe using __declspec(code_seg...) could help? (or maybe I'm wrong).
