The line it crashed on was

handler.c:1474

specifically the code

if (paf->type == sn)

which means paf, a pointer to an affect, was an invalid pointers. It may have been NULL or it may have just been freed before that pointer. Or it may have just been not correctly set.

Your backtrace yold you the stack of calls to get to that line of code.

It originated in a player zapping with a wand. It appears in the damage function the "do_sacrifice" function was called. (not sure why)
And inside of that function you have it trying to print thing and in act_color it ends up calling is_affected for whatever reason and crashing it.

You might start investigating that damage function and figuring out if do_sacrifice is calling the character perhaps after it was destroyed by some damage. Although the gdb report isn't going to be a magic answer to finding the problem. It's going to take some time and effort without knowing exactly what is going on in the code.
