When trying to execute following:
Xspice --disable-ticketing --xsession /usr/bin/xdm :1 --port 6900
(which I am far from sure if is correct)
xdm segfaults:
(gdb) bt

I will propose above patch to xorg, however since the issue was triggered by a wrong usage, I will not include the patch in the xdm package but wait for it to appear thru an upstream update. xdm has been around for quite a long time and this code has not caused issues so far - despite its ugliness. Fair enough, thanks a lot.
