Description of problem:
Attached is a simple program that leaks memory. compile it with 
gcc -g -omemtest memtest.c

Now when I run memprof on one computer is corretly shows the functions
in which the leaks are occuring like 

Function:         Self:        Total:
----------------- ------------ ---------------
__libc_malloc                0            3000
__libc_start_main            0           18000
_start                       0           18000
f                         3000            6000
fgh                          0           12000
g                         8000            8000
h                         4000            4000
main                         0           18000
malloc_hook_ini           3000            3000
----------------------------------------------

Now when I run it on another identical machine I instead get  only the 
__libc_malloc
__libc_start_main
malloc_hook_ini
entries and under the 'leaks' tab I get a lot of (???) as function name.

The strange thing is that this is not reproducable very well. If I
open up a different session on the same computer where it didn't work
before, it suddenly may work. I don't really know how to debug this
any further so I submit it here in case anyone would have any ideas
inspite of this somewhat confusing report (-:

Version-Release number of selected component (if applicable):
memprof-0.5.1-3

How reproducible:
Sometimes

Steps to Reproduce:
1. ???
