GetUserVariable reports incorrect value

[Ed the Bat]

GetUserVariable is returning false positives. Freshly-initialized variables should be zero, and checking it in DECORATE verifies this. But GetUserVariable is producing values that are very much not zero.

There appear to be further issues interacting with user variables from ACS. Calling SetUserVariable from ACS always seems to make ZDoom vanish.

This example has an ACS script that constantly logs the value of an uninitialized user variable on the player. If you press fire, the script sets it to 1. The correct value does get logged and displayed on the screen, and you can hear the monsters that are alerted, but it crashes immediately afterwards.

Actually the ACS might be another bug entirely. http://forum.zdoom.org/viewtopic.php?f=2&t=50731

Strangely I have not experienced that bug.

There might be the issue of ACS returning a non-initialized variable as well, one so far out that it may be causing the crash. At this point, though, I'm speculating.

All I can say for sure is that the user variable does indeed hold the correct value. A_JumpIf confirmed my example's variable to be zero, as expected. But GetUserVariable(); keeps returning some other value.

Fixed here.
