Could you compile malloc.c and popen.c with -g and reproduce the crash?
That would show the line numbers inside free and popen, which would be
helpful.

There seems to be something wrong with the output from symify (for one
thing, ct_upper.c has no function called free).  Are you sure it was the
exact same executable that crashed and that you gave to symify as
argument?
