| Have you tried using the malloc debugging?
Also you should be able to install valgrind into your own directory; try --prefix="/home/myhomedir/" on the configure script (set your home dir appropriately.) |

| All night last night i tried to find out how to malloc debug X_X someone told me i needed malloc.c so i searched and found nothing...
Edit: I noticed in comm.c MALLOC_DEBUG but i have no idea how to set that up..
Interesting enough... i kept recreating a char over and over and over and over till it crashed about on the seventh time without another command going through, crashed on the destroy. And the core file was different in a way. I'm pretty sure this is linked to the leak i'm dealing with.

| I'm almost positive at this point that something is being freed twice or you have mismatching hashed vs. unhashed allocation/deallocation.

Where did you see MALLOC_DEBUG? |

| The person that told me to get malloc.c was a friend from MSN but i don't think he knew what he was talking about o_0. As for MALLOC_DEBUG i see this in comm.c, but that's the only reference to malloc through the whole code. I read the manual for malloc in the shell and that stuff makes no sense to me -stupid- sorry x_x;. thanks.
/*
* Memory debugging if needed.
*/
#if defined(MALLOC_DEBUG)
malloc_debug( 2 );
#endif
~from comm.c ^^~ | | Top |

| Right. You need to edit your makefile to add a line defining MALLOC_DEBUG to 2. Or, you could edit mud.h and make the first line:
#define MALLOC_DEBUG 2 |

| Ok I added that line and I "make clean" then recompile, and i get this.
comm.o(.text+0x1f): In function `main':
/home/mud/dwd/smaug/src/comm.c:169: undefined reference to `malloc_debug'
comm.o(.text+0x6cd): In function `accept_new':
/home/mud/dwd/smaug/src/comm.c:522: undefined reference to `malloc_verify'
first error line:
/*
* Memory debugging if needed.
*/
#if defined(MALLOC_DEBUG)
malloc_debug( 2 );
#endif
second:
#if defined(MALLOC_DEBUG)
if ( malloc_verify( ) != 1 )
abort( );
#endif
I added
#define MALLOC_DEBUG 2
to mud.h and got those errors.. sorry I probably sound like the biggest moron in the world @_@. thanks.
