Hi, all,
I encountered some memory leak problems in my code performing SMIME operation on NT
reported by Purify. In order to identify the problem, I create a VC++ project smime.c
which is installed under openssl-0.9.6a/apps directory. This project only include
smime.c, apps.c, apps.h, app_rand.c. I am getting exactly the same memory leak
message, shown below
[W] MLK: Memory leak of 172 bytes from 1 block allocated in

if (inrand != NULL)
BIO_printf(bio_err,"%ld semi-random bytes loaded\n",
app_RAND_load_files(inrand));
mainCRTStartup+0x32d [crt0.c:206 ip=0x0040fc6d]
Does anybody have any suggestion on this? Is this a known problem?
If I put
CRYPTO_malloc_debug_init();
CRYPTO_dbg_set_options(V_CRYPTO_MDEBUG_ALL);
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON);
and
CRYPTO_mem_leaks_fp(stderr);
at the beginning and the end of the program, I got one more leak in
CRYPTO_malloc.
I searched through the archive, and found one message
http://marc.theaimsgroup.com/?l=openssl-dev&m=101118260003347&w=2
regarding RAND_poll on NT. Is this related with that problem? I would need to run
purify on Unix boxes also, does anybody know if the same problem exists on Unix?
Thanks in advance for any help. I am desperated with this problem because this is hold
up our release.
Kate
