Can anybody explain to me what happened lately? Is it a coincidence
that we had (at least?) two changes in the last couple of months which
trigger a 487 error on XP for no apparent reason?
How is it possible that an additional parameter to the calling function
can trigger an ERROR_INVALID_ADDRESS in a subsequently called Win32
function, even if this parameter is just a bool value not eve used in
the Win32 call?!?
Just for the records, I tested to remove the __stdcall and the regparm
from get_file_sd. I tried to replace the type bool with the Win32
typer BOOL and the native NT type BOOLEAN. I rearranged the code.
Nothing helps, except removing the additional parameter to get_file_sd.
I don't get this.
