Description (last modified by )
On some systems current code base traps with 'Privileged Instruction'. It seems this is at -
while ( !(__inpb(0x3F8 + 5) & 0x20) );
__outpb(0x3F8, *s);
(AB_log.h) in a part of the code which shouldn't be in release builds.
genmac.dim, wpacli.c.
The build system has to be improved that this special logging is only enabled by purpose and never makes it into release builds.
