AD2 Reloaded: viewtopic.php?f=19&t=73018
How to reproduce:
0. Get GZDooM g4.7.0pre-131-gc3772fe20 x64(not sure about x86).
1. Start Action DooM 2:UB by IWAD selector of GZDooM.
2. Start new game, select UB episode.
3. On the beginning of Map01, grab the Whiskey, drink or not drink it, no matter.
4. Use Alt. Attack(Secondary Fire) when holding the Whiskey bottle.
And BAM! GZDooM just crashed after switching kick and back to the bottle.
Official 4.6.1 and g4.7.0pre-101-g39513cf7a are fine, no crash, only the latest GZDooM build in DRDTeam SVN Build site triggered the crash.
