memory allocation / initialization of allocated memory

I just encountered something which may cause problems
to debugging memory allocation. You see I had a C code
with a lot of memory allocation/deallocation
and indirect addressing. Unfortunately I had 3 bugs
there. Running under Linux the compiler reported
*** glibc detected *** free(): invalid pointer:
This was not however the case with FreeBSD 4.11,
5.4 which didn't have a problem. Testing a simple
program which allocates doubles and/or ints I realized
that FreeBSD automatically initializes to zero the
memory which is allocated by malloc. This is default
behaviour I guess and I hope that it can be changed.
Otherwise we have problems tracking memory allocation
errors in buggy code.
Could somebody let me know how to change this default
Thanks in advance!
