I recompiled Apache-1.3.22 with mod_ssl-2.8.5 and OpenSSL-0.9.7-dev
today. Alas, I always get a core dump if I enable mod_ssl (as a DSO).
I traced it to the following point:
$ gdb sbin/httpd
(gdb) b ap_init_modules
(gdb) r -X -DSSL
...
(gdb) b ssl_engine_init.c:397
Breakpoint 2 at 0x2852042e: file ssl_engine_init.c, line 397.
(gdb) c
Continuing.
Breakpoint 2, ssl_init_TmpKeysHandle (action=0, s=0x8153034, p=0x815300c)
at ssl_engine_init.c:397
397 RSA_free(rsa);
(gdb) p *rsa
$19 = {pad = 0, version = 0, meth = 0x8142480, engine = 0x81f6de0, n = 0x81f6d40,
e = 0x81f6e00, d = 0x81f6da0, p = 0x81f6d60, q = 0x81f6e40, dmp1 = 0x81f6e60,
dmq1 = 0x81f6ea0, iqmp = 0x0, ex_data = {sk = 0x0, dummy = 0}, references = 1,
flags = 6, _method_mod_n = 0x0, _method_mod_p = 0x0, _method_mod_q = 0x0,
bignum_data = 0x0, blinding = 0x0}
(gdb) s
0x2851b108 in _init () from /opt/apache/libexec/libssl.so
(gdb)
Single stepping until exit from function _init,
which has no line number information.
Program received signal SIGBUS, Bus error.
0x823d082 in ?? ()
(gdb)
Is this an OpenSSL problem? Or a mod_ssl problem?
Puzzled, and recompiling openssl-0.9.7-dev with "-g" to supply more
traces,
Martin
