Found the last 36 bytes leak. It is a bug (I think) in nss_compat. When having compat in nsswitch.conf then I get this: ==12982== 156 (36 direct, 120 indirect) bytes in 1 blocks are definitely lost in loss record 22 of 32 ==12982== at 0x40208F0: malloc (in /usr/lib/valgrind/x86-linux/vgpreload_memcheck.so) ==12982== by 0x415CB4B: (within /lib/libc-2.6.1.so) ==12982== by 0x415D17E: __nss_database_lookup (in /lib/libc-2.6.1.so) ==12982== by 0x42C1EC9: ??? ==12982== by 0x42C282C: ??? ==12982== by 0x41183D1: getpwuid_r (in /lib/libc-2.6.1.so) ==12982== by 0x4117DEF: getpwuid (in /lib/libc-2.6.1.so) ==12982== by 0x804B4BE: main (dspam.c:127) ==12982== by 0x40A0FF1: (below main) (in /lib/libc-2.6.1.so) ==12982== by 0x804B350: (within /usr/bin/dspam) If I switch away from compat to files or add files in front of the compat entry then the memory leak (both of them. The 36 direct and the 120 indirect) go away :) Now I am down to zero memory leak with DSPAM. No matter what way I start or use DSPAM. :) I still have a long way to go till I have all memory allocations under control: ==13028== malloc/free: 13,371 allocs, 13,287 frees, 4,002,198 bytes allocated. But still. At least valgrind is not reporting any memory leaks. > My initial installation had around 324 bytes memory leak every time dspam > was called.
