Comment:

 Well, that's pretty weird.  My first guess would be some mismatch between
 the Tor and OpenSSL packages, but I don't know at all what that might be,
 or why it wouldn't have been noted.  OPENSSL_cpuid_setup() is a really
 basic function for OPENSSL; it shouldn't be able to fail like that.

 If it's possible to try building Tor from source, that might make it
 possible to rule out the idea that it could be a packaging problem.  That
 is, if Tor built from source works, then there's some issue going on with
 package compatibility.  If Tor built from source doesn't work, then we've
 got a problem in Tor or in the openssl library.

 Here's another little test program to tell if your openssl is *completely*
 broken.  If this one crashes, it's definitely OpenSSL's fault.  If it
 doesn't, then the problem might lie somewhere else:
 {{{
 #include <openssl/engine.h>
 #include <openssl/evp.h>
 #include <openssl/err.h>

 int main(int c, char **v)
 {
     ERR_load_crypto_strings();
     OpenSSL_add_all_algorithms();
     ENGINE_load_builtin_engines();
     ENGINE_register_all_complete();
     puts("Stuff seems okay.");
     return 0;
 }
 }}}

 (It should build okay with "gcc -Wall -lcrypto test.c -o test")
