>Description:

Trying to boot a -current kernel dies with:

NetBSD 5.99.60 (DEAD) #45: Fri Jan 20 20:58:09 CET 2012
        
martin%night-porter.duskware.de@localhost:/usr/src/sys/arch/vax/compile/DEAD
MicroVAX 4000/90                                                          
total memory = 127 MB
avail memory = 122 MB
panic: Segv in kernel mode: pc 0x80085add addr 0xbb973bdc

addr2line says this is crypto/nist_ctr_drbg/nist_ctr_drbg.c:297

which is:

               memcpy(&temp[0], &nist_cipher_df_encrypted_iv[j][0],
                       NIST_BLOCK_OUTLEN_BYTES);

and temp is pointing into buffer, which is

        unsigned int buffer[NIST_BLOCK_SEEDLEN_INTS];

Is this a stack overflow?

>How-To-Repeat:

Just try to boot a -current vax kernel

>Fix:
n/a
