Not sure this is present in 6.3, so check first. A quick sysctl 
security.bsd.map_at_zero will return a value of 0 if present. As RW 
indicated it may have been included in the p13 update. 

To elaborate a little, you may need to toggle the security.bsd.map_at_zero: 
0 MIB. Change this to 1 to disable, not sure if loader.conf or sysctl.conf 
is the right place. Would be better not to have to do this because leaving 
it enabled is a security feature. However, WINE may not run without it.

I'm also not sure if the following is related, I just recall reading about 
it at in the same time frame and mostly with regard to Samba. Possibly there 
is a need to place CONFIGURE_ARGS+= --disable-pie in make.conf and recompile 
WINE. This may not apply to WINE at all so if the MIB config mentioned above 
fixes the situation do not proceed with this. I suspect wrt to WINE this is 
irrelevant, but thought I'd mention it anyway.

Should you discover --disable-pie is required leaving it present in 
make.conf is not a very satisfactory arrangement, as it would then apply to 
all ports. Workaround would be to place it just for WINE recompile if 
absolutely necessary and then comment it out when done.
