We were using OpenSSL in our product, but lately after testing on Vista,
our application was was crashing (only in Vista) in SSL_Connect(). (It
worked fine in XP)
After debugging through OpenSSL we found that within RAND_poll() it was
crashing in a win32 api function snap(TH32CS_SNAPALL,0).
...
Has anyone else faced such RAND_poll() related crash before ?
There was another report about RAND_poll in Vista, but trouble is that
it's irreproducible in simple test applications.
Is there anyway I can bypass that RAND_poll() call (as described in the
last paragraph of
http://www.mail-archive.com/openssl-dev@openssl.org/msg18900.html).
Can you test if below code makes your application work by appending it
to crypto/rand/md_rand.c? Idea here is to call RAND_poll from code which
is [believed to be] serialized by Windows. A.
#if defined(_WIN32)
#if defined(__GNUC__) && __GNUC__>=2
static int premain(void) __attribute__((constructor));
#endif
static int premain(void)
{
if (!initialized)
{
RAND_poll();
initialized = 1;
}
return 0;
}
#if defined(_MSC_VER)
# if defined(_WIN64)
# pragma section(".CRT$XCU",read)
__declspec(allocate(".CRT$XCU"))
# else
# pragma data_seg(".CRT$XCU")
# endif
static int (*p)(void) = premain;
# pragma data_seg()
#endif
#endif
