After patching away the complete smartalloc stuff, valgrind was able to produce some results which looks not completely bogus:
| ==3612== Invalid write of size 1

This looks like buffer overflow.
Can someone please explain why bacula needs its own memory check stuff
which don't gain many but breaks external debuggers like valgrind?
