[gccsdk] OpenSSL issues

Hi

I'm trying to track down an issue with ssl in python, which used OpenSSL
1.1. To try to reduce the number of moving parts, I've managed to narrow
it down to a smaller test.

The setup is .. the C code below (which runs fine on linux) has been
compiled on RISC OS (native) with GCC10 (buult from the auto builder).
LibSSL (1.1.0) is the one I built with the auto-builder, but I had to
tweak it to use the 1.1.0n (rather than m) sources and I built it for
armv6z (IIRC) instaad of armv3.


#include <openssl/ssl.h>

int main(void)
{
SSL_CTX *ctx = SSL_CTX_new( TLS_client_method() );
printf("ctx: %x\n", ctx);
printf("load_verify_locations: %d\n",
SSL_CTX_load_verify_locations(ctx, "cacert.pem", NULL) );
SSL_CTX_free(ctx);
printf("Bye!\n");
}


*gcc -c ssltest.c -ILibSSL11:
*gcc ssltest.o -o ssltest -LLibSSLl11: -lssl -lcrypto -ldl
*ssltest
ctx: 71a88

Fatal signal received: Segmentation fault

Stack backtrace:

If I rename the pem file, it reports SSL_CTX_load_verify_locations: 0
(which one would expect) then has a similar error (wihtout pritning Bye!)


Anyone any ideas?

Cheers

Chris
