I have tested plugin on my dedicated machine on lvdm gamemode, and worked fine - showed AMX backtrace. Than i made same code on my gamemode, there gamemode crash but wont show what is problem.

error code on main():
new blabla = 51618;
new nest[100] = 1;
nest[blabla] = 1;

crash log with test gm:
[01:51:55] [debug] Run time error 4: "Array index out of bounds"
[01:51:55] [debug] Accessing element at index 51618 past array upper bound 99
[01:51:55] [debug] AMX backtrace:
[01:51:55] [debug] #0 000000dc in main () at C:\Users\Y_D_Komp\Desktop\3.0 CHRP SP\gamemodes\lvdm.pwn:91
[01:51:55] Script[gamemodes/lvdm.amx]: Run time error 4: "Array index out of bounds"

crash log with productiongm.amx:
[03:18:39] [debug] Run time error 4: "Array index out of bounds"
[03:18:39] [debug] Accessing element at index 51618 past array upper bound 99
[03:18:39] [debug] AMX backtrace:
[03:18:39] [debug] Server crashed while executing productiongm.amx
[03:18:39] [debug] AMX backtrace:

test gm(lv dm) have about 1000lines
productiongm.amx gm have about 120 000 lines

Does number of gamemode lines have something with not showing AMX backtrace? Or something else...
Includes are not problem, becasue i included same includes on both gamemodes, and i tryied -d3 and -d2 flags...

Zeex commented

Which version are you using?

zoransalamun commented

Latest version, i downloaded yesterday crashdetect-4.10-linux.tar.gz and tested... this problem happend before also, and my gamemode is to bih to rewrap lines with notepad++, i need days for do that...

I tested lvdm few hours ago, and when i have more than 65and something thousands lines, crashdetect plugin wont print line in gamemode...

zoransalamun commented

I have new information, i think that problem with line numbers is only with linux version. On windows server even wont crash on wrong array index, on linux is same only if number of gamemode lines is under 65535 lines

Can that be fixed? Or i must reduce line numbers in gamemode?

Zeex commented

There's a patch for the pawn compiler here: https://github.com/Zeex/pawn-3.2.3664_patches/tree/master/not_samp_compatible (actually in two files) that fixes that limitation but you'll have to re-compile crashdetect as well (with the new header) to make it work.

zoransalamun commented

Ok, thanks, i will test it today

zoransalamun commented

"but you'll have to re-compile crashdetect as well (with the new header) to make it work." - can you tell me how to compile crashdetect plugin with new header? what i must change frow original source and how?

Zeex commented

If you already patched the compiler then you just copy the new amxdbg.h from pawn/source/amx/ to crashdetect/amx/ and build crashdetect

zoransalamun commented

Ok, i have downloaded new patched compiler from link(Pre-compiled binaries): https://github.com/Zeex/pawn-3.2.3664_patches

Now where can i find new amxdbg.h to recompile crashdetect plugin?

Zeex commented

Those binaries contain only SA-MP compatible patches, so you have to patch it yourself adding the patches from not_samp_compatible/ (just use apply_all.sh instead of apply_compatible.sh)

zoransalamun commented

Ok, i have try, but its not working. Can you tell me did i do something wrong:
1.) I have follow Build Instructions on this link: https://github.com/Zeex/pawn-3.2.3664_patches
- And compile with apply_all-sh
2.) Downloaded crashdetect master
3.) Replaced amxdbg.h in crashdetect/amx/ width amxdbg.h from pawn patches
4.) Compile crashdetect plugin i got crashdetect.so
5.) Placed in plugins folder
6.) Recompile samp gamemode with new pawncc

And everything is the same, its not showing information about crash.

I have try -d2, -d3 flags, nothing, its still problem with number of lines in gamemode...
Tested on Ubuntu and Centos.

Do you have solution? Did you tested any gamemode with more than 65535 lines?

Zeex commented

Hontestly I've never tested a gamemode with more than 65k lines with that compiler but I'm sure it should work.

Are you sure all the patches have been applied? I've just found a minor mistake in that script that was preventing the not_samp_compatible patches from being applied (seems like I forgot to test in combination with apply_all.sh).

Anyway, I'm going to build the compiler with those patches and upload new binaries today, stay tuned.

Thanks, i will test later on centos and ubuntu with compiling crashdetect plugin with new amxdbg.h.

zoransalamun commented

Thanks Zeex, i have recompiled plugin for ubuntu and everything is working fine.
