Dear list, 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 instructions and indirect addressing. Unfortunately I had 3 bugs there. Running under Linux the compiler reported *** glibc detected *** free(): invalid pointer: 0x08056aa8 *** 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 behaviour? Thanks in advance! Symeon! Yahoo! Mail Stay connected, organized, and protected.
