My Location Mod on Windows vs Linux

[Purple Elephant1au]

Hi

This is been frustrating me for awhile now , and i keep going back to it every few days as to try and find an answer to the problem

Ok Problem is

I have this mod ( location helper mod ) for freezetag , which works as it should when im testing on a windows server but whenever i upload it to my Linux server ( public )
it crashes the server.

I highlighted when i turned the mod on ( which is in the spawn event ) so it registers the spawn event but wont do anything if cvar not set , spawn event works fine if cvar not set.

Error code from console log

The servers ( local and public ) have the same pk3 in them , both exec the location mod from spawn event but it only works on Windows version

I cant tell what the error is saying , i thought it had something to do with the ihuddraws , so i tried changing index numbers a few times but same problem
Ive run out of ideas , fresh eyes anyone

Ill attach the location_help.scr

I see you've done some println(), which is good, may I suggest putting them in more loops though to better assist where the issue could potentially be.
At first glance I can't really tell, and if it only crashes on *nix, then maybe the segmentation fault is on our end with the patch. Perhaps RR can assist better with this.

BTW, your ingame name "PurpleElephant ( . Y . )" priceless.

When you call ihuddraw_shader, initialize variable holding string first. I bet you have some variable like local.shader which is sometimes NULL or NIL. You have to initialize this variable.

If you don't have a variable but you pass string directly, you should use variable.

Stacktrace shows clearly where it crashed and why:

--> ./fgameded.so(STR_GetText+0x6) [0xf6491a0f]
--> ./fgameded.so(ST_iHudDrawShader+0x112) [0xf6491efa]

Also faulty address is (nil) means that it crashed because of some NULL variable.

Isn't it weird that Linux won't accept a constant string? Are there more commands that are sensitive to this? I only test on windows as well.

[Razo[R]apiD]

Well, this can be a problem on my side, I'll have to add some protection against this.

Thanks , i used varibles and it works now , stupid thing lol
