Code: Select all

004933D3  warzone2100.exe:004933D3  world_coord  /tags/2.2.1/src/map.h:225
0049446A  warzone2100.exe:0049446A  moveUpdateDroid  /tags/2.2.1/src/move.c:3078
Um... we're missing a few intermediate function calls...

moveUpdateDroid calls moveDroidTo which calls moveDroidToBase which calls world_coord a whole bunch of times, none of which look like a possible an access violation.

Well, apparently a lot of people are getting this bug. I have no idea... I wish Buginator would come back. :(

What exactly is an "access violation" in Windows? I've looked at this and some other Windows crashdumps, and when I look at the code it supposedly crashed in, it looks like something completely harmless that shouldn't even be able to crash the game...

i have no idea what it is - the only error report that comes out is what i have put up here... no other. and there is no warning - just a complete out of game to the desktop - no ms error report eithe. :stare: i thought maybe it was due to one or more of the ai trying to build something on top of something elese... i have seen that happen more than once... other than that...dunno.

access violation == segfault. It's what happens when you try dereference a pointer that points to an invalid memory address.

I'm completely lost by the code it crashed in, too. It doesn't even make sense:

004933D3 warzone2100.exe:004933D3 world_coord 2.2.1/src/map.h:225
0049446A warzone2100.exe:0049446A moveUpdateDroid 2.2.1/src/move.c:3078

move.c:3078 doesn't call world_coord at all, it calls moveDroidTo (which could plausibly be skipped with moveDroidToBase, but that's not an inline function; maybe it got inlined somehow? It's plausibly a bug in moveDroidToBase, do you see anything there?)

That's what I guessed, yes. I just wanted to make sure, because the indicated code in this (and a few other) crashdumps cannot segfault.

004933D3 warzone2100.exe:004933D3 world_coord 2.2.1/src/map.h:225
0049446A warzone2100.exe:0049446A moveUpdateDroid 2.2.1/src/move.c:3078

Well, moveUpdateDroid calls moveDroidTo which is basically an (unecessary?) alias for moveDroidToBase, which calls world_coord four times (src/move.c:385-388,396-399):

Code: Select all

fmx2 = psDroid->sMove.asPath[psDroid->sMove.numPoints -1].x;
fmy2 = psDroid->sMove.asPath[psDroid->sMove.numPoints -1].y;
fmx2 = world_coord(fmx2) + TILE_UNITS / 2;
fmy2 = world_coord(fmy2) + TILE_UNITS / 2;
fmx1 = psDroid->sMove.asPath[psDroid->sMove.numPoints -2].x;
fmy1 = psDroid->sMove.asPath[psDroid->sMove.numPoints -2].y;
fmx1 = world_coord(fmx1) + TILE_UNITS / 2;
fmy1 = world_coord(fmy1) + TILE_UNITS / 2;
Maybe the compiler optimized those as (example for the first and third line)

Code: Select all

fmx2 = world_coord(psDroid->sMove.asPath[psDroid->sMove.numPoints -1].x) + TILE_UNITS / 2;
and inlined world_coord, then we have

Code: Select all

fmx2 = (psDroid->sMove.asPath[psDroid->sMove.numPoints -1].x) << 7 + TILE_UNITS / 2;
If that theory is correct, the problem is that psDroid->sMove.asPath[psDroid->sMove.numPoints - 1] is invalid (though I have no idea how that could happen). If not, the debug info is complete garbage.

Do you happen to have a savegame that can reliably reproduce this bug?

psDroid->sMove.asPath[psDroid->sMove.numPoints is 0, since the droid can't build there, and when we -1 it... (or -2) then boom.

See http://developer.wz2100.net/changeset/7822
This will make it so it don't crash... but the real problem still needs to be fixed. (the droid shouldn't be going to that location to build, since it is a invalid location)
and it ends here.
