[R3862 and up] Crash instead intro dialogue

[Dwachs]

Apparently DrMingW does not work with symbols generated by current gcc compiler with option '-g' :(

@Wernieman: could you please compile such a debug executable but with option '-gstabs' instead of '-g' ? Thank you!

[wernieman]

O.K.

I added to the config.default:

Code Select Expand

CCFLAGS += -gstabs
CXXFLAGS += -gstabs

file: sim-win-debug-3995.zip
download: http://www.wernieman.de/sim-win-debug-3995.zip
size: 22 MByte
include: sdl and gdi

[Dwachs]

Thank you very much! Hope this helps to locate the crash

[Václav]

Small stupid question: with which options to start debug version of game?

[Dwachs]

Every combination that leads to a crash and a crash report from drmingw is good

'-debug 3' is ok.

[Václav]

Thanks.

[Milko]

Hi

With 3995 -gstabs, drmingw report the same error of 3991 (no symbols...)
(for gdi and for sdl)

sim-wingdi-3995.exe caused an Illegal Instruction at location 005fb079 in module sim-wingdi-3995.exe.

Other tests
A) I start simutrans with -load pressing "p" key, next I try to start a new world, game crashed, I attach the logs, could help?
B) I start simutrans with -load pressing "p" key, next I try to run actual world (exit the pause), game crash....

How bad :( Did you use the drmingw version from here:

http://code.google.com/p/jrfonseca/wiki/DrMingw ?

Edit: drmingw is also contained in this package:

http://sourceforge.net/projects/mingw/files/MinGW/Utilities/mingw-utils/mingw-utils-0.3/mingw-utils-0.3.tar.gz/download

I do not know, which of the two versions is the most recent one.

[Milko]

Hi

Yes, drmingw 0.4.4

I use
drmingw -i
At crash appear a window with three buttons "debug","don't send","send", I click debug.

My two new "logs" can you help?

Giuseppe

[Dwachs]

No call stack in that window ?

The logs are helpfuls as they show, where the bug is not. :/ I will have to add further log messages soon.

Edit: Revision 4000 has some more debug messages, please run test with '-debug 4' with the next nighlies.

[Milko]

Call stack section is blank... Only registers are shown.

It may be that the bug manifests itself in a dll and then drmingw do not see any data?

Giuseppe

[wernieman]

Did you need more "special nighty's"?

[Dwachs]

Call stack section is blank... Only registers are shown.

Could be. Googling tells me that in such case drmingw tell something like

Code Select Expand

pidgin.exe caused an Access Violation at location 7626ce0a in module msvcrt.dll

[Milko]

In my crash error is in module sim-wingdi-3995.exe; it appear to be in simutrans, and not in a dll....

Giuseppe

[prissi]

Not if it is SDL, as simutrans main is called from SDL and thus both run under the same context.

Please try also the following executable: http://www.physik.tu-berlin.de/~prissi/simutrans/sim.zip

[Václav]

Splendid...

The first comment: It runs by me.

The second comment: I have to test it more for possible else bugs. The first one I found is crash after using of "windows key". I wanted to keep game running and so I used that key and after switching back to game, it crashed. Soon I will give more reports.

Intro dialogue needs better face.

-->
Game freezes after some time after some actions (still not fully identified). But it may be caused by game age - number of moving vehicles (about one thousand), transportation web size and so on. So it seems I am going to have to begin new game.

[prissi]

Since this was build on windows, maybe we have run into a compiler or library bug in the Mingw Linux build. Probably a new version of those tool chains may solve this; but as werniman is quite busy, I am afraid we might first release a new stable before you could use the nightlies on your specific system.

[wernieman]

If you want I could try to make a new mingw-Compiler ......

btw:
Yesterday I get my contractual notice of dismissal

(De: Ist das richtiges englisch für "Ordentliche Kündigung erhalten"??)

So after 1.1.2011 I have enough time for it ;o)

[Milko]

Hi

Very good!, new version work also for me  .

Giuseppe

[prissi]

Aparently the Mingw linux system has a bug on certain windows configurations. Not sure, how to handle that. Maybe a newer Mingw build can help this.

[wernieman]

I will try ... next week ...

[wernieman]

Sorry, but only next week .....

Edit:
..... now ;o)

please test next nightly!!

[Václav]

Number 4047 runs by me.

[Milko]

Hi

WOW!!!!

4059 it's ok!

Thanks

Giuseppe

[An_dz]

R4059 is working for me too.

Thanks for the work.

Now new stable Simutrans can be lauched!

[Dwachs]

Yeah !!!!! 

[Václav]

Of course.

But I will have to begin new game. Because in currently played game I achieved point where it became boring - especially if some days ago I began creation of railway station extension of such size that I cannot place it anywhere.

[wernieman]

Next year (January) I update SDL too .....
(I hope)
