>Description:
	I just had a build of pkgsrc/security/ssh on a Alpha running -current
	stop, with top showing:

  PID USERNAME PRI NICE   SIZE   RES STATE     TIME   WCPU    CPU COMMAND
  23171 root     104   20    71M   72M run      20.3H 99.02% 99.02% conftest

	conftest was run by configure, conftest.c is:

--- snip ---
        #include <string.h>
        #include <openssl/rand.h>
        #include <openssl/rsa.h>
        #include <openssl/bn.h>
        #include <openssl/sha.h>
        int main(void)
        {
                int num; RSA *key; static unsigned char p_in[] = "blahblah";
                unsigned char c[256], p[256];
                memset(c, 0, sizeof(c)); RAND_add(c, sizeof(c), sizeof(c));
                if ((key=RSA_generate_key(512, 3, NULL, NULL))==NULL) return(1);
                num = RSA_public_encrypt(sizeof(p_in) - 1, p_in, c, key, RSA_PKCS1_PADDING);
                return(-1 == RSA_private_decrypt(num, c, p, key, RSA_PKCS1_PADDING));
        }
--- snip ---

	i'm not a guru on either alpha nor the whole crypto code, can you
	think of anything that could hang this? By putting in some printf()s,
	it seems the RSA_generate_key() call is the problem.

	This is on 1.5E/alpha using libs from /usr/lib (cc r.c -o r -lssl
	-lcrypto).  It does *not* happen on 1.5_ALPHA/i386.

	BTW, can't we teach libssl to pull in libcrypto automatically?


>How-To-Repeat:
	Compile the above program, run it. Wait. 
	(On my P133 it runs <5 seconds).

>Fix:
	Unknown.
