OpenSSL 0.9.8a dumps core in SSL_CTX_load_verify_locations()

Marko Asplund
hi

I'm having problems with the OpenSSL SSL_CTX_load_verify_locations()  
routine dumping core on Solaris 8 (sparc, 64-bit). I first noticed  
this problem with Apache mod_ssl but it can be reproduced with a  
minimal standalone C program which calls SSL_CTX_load_verify_locations
().

I've only experienced this problem with one certain CA bundle file.  
The problem doesn't appear with OpenSSL release 0.9.7e (and at least  
d) but starting with f I'm getting core dumps (tested with i, g, f  
and 0.9.8a).

Any ideas on what has changed between 0.9.7e and 0.9.7f that may be  
causing this?

Here's the code for reproducing the problem:

/*
   export PATH=/opt/local/gcc/4.0/bin:$PATH:/usr/ccs/bin:/opt/sfw/bin
   export or=/home/aspa/tmp/openssl098a
   coreadm -p core $$
   gcc x509catest.c -g -m64 -I$or/include -L$or/lib -lssl -lcrypto -
lsocket -ldl
   ./a.out
*/
#include <openssl/ssl.h>
int main() {
   char *capath="/home/aspa/kronodoc/dev-3.4/httpd/conf/ssl.crt";
   char *cafile;
   cafile="/home/aspa/kronodoc/dev-3.4/httpd/conf/ssl.crt/bundle.crt";
   cafile="/home/aspa/kronodoc/dev-3.4/httpd/conf/ssl.crt/ca-
bundle.crt";
   SSL_load_error_strings();
   SSL_library_init();
   SSL_CTX *ctx = SSL_CTX_new(SSLv3_method());
   int r = SSL_CTX_load_verify_locations(ctx, cafile, capath);
   printf("SSL_CTX_load_verify_locations: %d\n",r);
}


Here's the stack backtrace from the core file:

Here's the exact build procedure I'm using to build OpenSSL:

# build OpenSSL
export PATH=/opt/local/gcc/4.0/bin:$PATH:/usr/ccs/bin:/opt/sfw/bin
perl Configure solaris64-sparcv9-gcc no-idea no-shared -g -fPIC --
prefix=/home/aspa/tmp/openssl098a
gmake depend
gmake
gmake test
gmake install
