Look at screen!
System: WinXP/32 bit
Command for logging: logfile 2
Game ver.:ufoai-2.4-dev-1301086950-Debug-pentium3-O1-sse-7z-full-win32.exe
The error appears when I press to finish a course after murder of last enemy.

OK, confirmed in a recent compile on Windows (NOT Muton's last build that IIRC is ~ a month old).

Pressing the "end turn" key right after killing the last alien, but before any resolution-type of screen comes up, freezes the game.

I could do this by simply starting a skirmish that only had one alien to start with.

I'll toss in my experience with this bug as well. I'm running Vista and 2.4-dev. I installed the game using http://ufoai.ninex.info/snapshots/ufoai-latest-win32.exe , and updated just the binaries on April 11 with http://ufoai.ninex.info/snapshots/ufoai-latest-win32.zip .

You can actually issue commands after the last alien is killed, but only for a brief moment. The freeze occurs if you try to take action while the game is adding up experience points for that mission, which starts ~1 second after the last kill. As a workaround, I've started opening up the console after a few kills to see if it's running the experience totals. That's where the delay between the last kill and the victory screen comes from.

I can share my ufoconsole.log if needed. I just intentionally froze the game and the log file has no error messages. It cuts off with the experience points it had totaled when I told one of my soldiers to move, that's it. It occurs reliably in campaign and skirmish mode.

OK, it might be time to dust off ye olde GNU debugger.  I admit I haven't done so in quite some time, I'll have to see if I can get it (the debugger) working again.

Does anyone running a NON-Windows OS have this issue, if they follow the steps mentioned?

I also use *buntu Linux on some of my systems, but I don't have UFO: AI set up on them at the moment.

Having just made the transition from playing UFO on Windows Vista to playing it on Fedora, I noticed that the experience points are calculated almost instantly under Fedora. The total time between the last alien dying and the victory screen appearing is around two seconds, and virtually none of it is from the experience points. In Windows, it could take upwards of 10 seconds to total the experience. If most of our developers are using Linux to play the game, then this might explain why they have trouble reproducing the bug for themselves.

My temporary "hotfix" is every time I kill an alien after 2-3 (fighters and scouts) or 4-5 (harvesters and up) go get a sandwich. If the game is still running there's at least one more.

I can move the mouse usually, though, without a crash. Are these seperate issues? (game taking up to a minute or so to register all enemies dead [not up to incapacitation yet so can't offer insight] and end mission?)

I had a similar issue when killing the last enemy.
The round ended abruptly, and the Firebird went back to base to refuel.
No bonus, no promotions, and no ship acquired.

I got this bug. I messed with SendNotifyMessage to fix it, then found tlh2000s patch which is ok so far. I manually applied the patch as I've not figured out git yet. I've done about 5 missions and gone a tad crazy at the controls after killing the last alien. It's much faster counting up the stats and exiting.

Hmm, maybe I spoke too soon. I now occasionally get this lot when the mission ends:

yes the dbuffer is not yet locked - this is a todo comment in latest revision

can you send a patch for your SendNotifyMessage solution?

How is this applied? (Let's start with assuming I know nothing about coding but advanced general computer use) This bug is my #1 enemy recently.

@Mattn

The bug is fixed!
A patch is available in the "Win32 Development Binary Installer Links" topic ....

---------------------------------

git checkout .
reverse your mods (they are lost)

git checkout master
if you are not on the master branch

git fetch
to get all updates

git pull --rebase
to apply fetched updates to your current branch

but thats the wrong forum to ask
do it there

Fix appears to break in-base radar

*EDIT* Fix appears to permanently break all the in-base radar in the savefile the first time a UFO wanders out of radar range, and also seems to remove the ability to find missions as they're happening. Definitely still losing aircraft though.
