> 
> A memory leak was detected using the AddressSanitizer tool, when running
> the crypto-perf application with a test vector file.
> 
> The strdup function used returns a pointer to a null-terminated byte
> string, which must be freed after use. This patch frees the pointer in an
> error case, and also after a successful run.
