 Forums >>  Brainstorms - General  >>  IDA Database Corruption....

Topic created on: December 10, 2006 06:51 CST by doekia .

My database get corrupted (may be due a change I made in my processor module).
I currently have FUNCTION CHUNK with no name.
When I try to delete them nothing happen
If I try to move them or manipulate the caller function:
Access violation at 1006D401 in IDA64.WLL
I have try delete all: does not fix
Delete all segments and recreate: more access violation

If any one got an idea that will be great. My database is pretty big and involved so many manual operations it will take ages to recreate it from scratch.

Never get served better than by yourself... :-)

I post the response in case it might help somebody else.
I put the following snippet of code inside my ana().
Then I did a text search for THUNK and responded yes all the times et voila.

d--

---8<----- snippet ----8<----
  if (1) /// I got some problem with tail-chunk loosing their head - FIXUP code
     {
       static int no_reenter = 1;
       volatile func_t * x=get_fchunk(cmd.ea);
       if (x != NULL)
          {
            char buf[MAXSTR];
            buf[0]=0;
            msg("A func chunk...\n",buf);
               {
                 get_func_name(cmd.ea, buf, sizeof(buf));
                 msg("A func tail... '%s'\n",buf);
                 if (no_reenter--)
                 if (buf[0]==0)
                    {
                      msg(" owner=%08X\n",x->owner);
                      if (askyn_c(0,"Orphan func tail detected!\nDo you want to remove?")==1)
                         {
                           funcs.del_area(cmd.ea,0);
                         }

                    }
                 no_reenter++;
               }
          }
     }
