r2934 crash when zooming

I'm using the latest version on the trunk r2934 with the nightly version of pak128: 779. Compiled with gcc-4.3.4 on gentoo linux.

The problem happened when accidentaly my finger p****ed over the right side of the touchpad which zooms. The game crashed and this is the messages since the beginning:

Violación de segmento

The last means Segment violation for those who doesn't speak Spanish... This happened also yesterday night but I didn't know way thus way I executed it today on the terminal to see if it could help understand what happened... And as I see it it remember that it happened when I used the wheel of the mouse... I'll recompile it now with DEBUG = 3 and try to reproduce it... But it's hard to do it... So long I haven't been able to do it... Anyway it's related to the depot, since I'm renewing the tram lines in my cities and both times it was selected... If you need it I can upload the savegame...

I am getting the same error with pak64 on r2934 compiled on debian/squeeze with gcc 4.3.4. As T0m4s reported, the console output immediately preceding the segfault is
Code: [Select]
set_zoom_factor() : set 2 (4/3)

could you provide a backtrace with gdb?
Parsley, sage, rosemary, and maggikraut.

Unfortunately the behaviour that is consistent outside gdb (zoom in then segfault) does not occur when running simutrans inside gdb.  I have however gleaned a small bit more of info. If I zoom out before ever zooming in, then the segfault does not occur. It is only if my first zoom action is an inwards zoom that the problem occurs.

Actually the bug is quite difficult to reproduce... But after several tries I've managed to do it under gdb. Here's the info with the backtrace: (I've reproduced it with the new version on the trunk r2935)

One question. Are you using bigger size addon ?
If you are using 192 or 255 size addon and which is on screen, it will crash.
This is a known problem.

I'm using no addons. Just the nightly version of pak128.

Pak128 airplanes are 176*176... no addons needed.

(btw, this crash does not happen on windows... but that's not important)

My projects... Tools for messing with Simutrans graphics. Graphic archive - templates and some other stuff for painters. Development logs for most recent information on what is going on. And of course pak128!

I didn't know... Anyway in this map i still have no planes... Are there other things in the pak that can cause this in addition to planes? Anyway sanna had the same problem with pak64, but maybe there's something on pak64 bigger also...


I've just discover another thing... If you load any savegame and the first you do it's zoom in, it crashes. If you zoom out, then you can zoom in without problems. Anyway this happens just with the gcc4 version. I've downloaded the gcc3 and gcc4 r2935 nightly version and it happens only with the gcc4 version. And with the old version RC102.2.1 r2896 gcc4 this doesn't happen. :S

@Tom4S and z9999: would you please provide a savegame, which crashes reproducably after zooming in?

@Tom4s: could you please retest with revision 2942?

r2942 doesn't launch for me.
I could build but ****embler complained.

Does this patch fixes this?

I had to change line 1791 in simgraph16.cc to
Code: [Select]
"jmp *(%2)\n\t"
to get the code with asm compiled. However, simutrans crashes with the asm code for revision 2930 and 2942.

Yes, launched.

BTW, recent code in simgraph16.cc and simworld.cc have many signed and unsigned warnigs.

I tested it on r2942 with the pathc (without patch it crashed) and apparently it works.

Thanks :)

Seems you all beat me to it... but for the sake of completeness *smile*, here is what happened when I tried to run r2942:

Built r2942 on debian/squeeze, gcc 4.3.4, game compiles fine, but upon launch this happens:
Code: [Select]
$ ./simutrans --debug 3 --log 3
Reading low level config data ...
p****_simuconf() at config/simuconf.tab: Reading simuconf.tab successful!
Preparing display ...
Screen Flags: requested=10, actual=10
Loading font 'font/prop.fnt'
font/prop.fnt sucessfully loaded as old format prop font!

running in gdb gives

Dwachs patch above prevents the crash at launch of 2942, and the zoom crash also seems to have been fixed, but there is as z9999+ observed quite a few warnings about comparisons between signed and unsigned integers:
Code: [Select]

The inline ****embler requires uint32 for runlen, which was changed to PIXVAL instead its needed siye. Should work again in r2943.
