[Fixed] r28676 unable to run in debugger

[mark.hawrylak]

I cannot start the game in debugger, this issue is only occuring when I am running the game in the code blocks debugger
running code blocks version 5731.
I have also tested and am experiencing the same issue when I remove my C:\Documents and Settings\mark\Application Data\UFOAI folder

I am downloading the new code blocks download and will report my results here.

[mark.hawrylak]

the issue is resolved after I downloaded codebocks 6088 from the forum
please note that the code blocks from the wiki 
http://mattn.ninex.info/download/codeblocks.zip
on the page http://ufoai.ninex.info/wiki/index.php/Code::Blocks is version 6080 which does not work properly

this version
http://www.destructavator.com/92dl/codeblocks_6088.zip
from the form post http://ufoai.ninex.info/forum/index.php?topic=4282.30 is the correct code blocks to use.

i've fixed the other files - thanks

I am still getting the above segfault with codeblocks 6088 version.
I have another reproducable segfault to report, but I cannot report it while I cannot enter a map in debugger.
I can at least start the game, the issue occurs while entering a skirmish map.

        changeListener2 = 0x251f12
        changeListener = 0xfeeefeee
        hash = 40
        var = 0x2a1d1f1c
        previousVar = 0x0

I got the same error message.

I havn't touched C-Code for a long long time, but i think there is a reason for this message.

If you look a the code (cvar.c line 317 - 323)

         Mem_Free(var);
         changeListener = var->changeListener;
         while (changeListener) {
            cvarChangeListener_t *changeListener2 = changeListener->next;
            Mem_Free(changeListener);
            changeListener = changeListener2;
         }

First var is freed and then it is accessed.
As a solution I moved Mem_Free(var); after the while block.

thanks - stupid bug - fixed in r28678

[mark.hawrylak]
