Hi,
After multiple calls to ERR_load_crypto_string(),
we cannot get error message using ERR_error_string().
A short sample is as follows:
=====
#include <openssl/err.h>
int main()
{
ERR_load_crypto_strings();
printf("%s\n",ERR_error_string(101163138,NULL));
ERR_free_strings();
ERR_load_crypto_strings();
printf("%s\n",ERR_error_string(101163138,NULL));
return 0;
}
=====
This is a bug, isn't it?
multiple calls to ERR_load_crypto_strings() are harmless
(well the function is not reentrant but that's not important
here) the problem is that you call ERR_free_strings() between
these two calls. ERR_load_crypto_strings() sets a static
status variable once it has been called so that every further
call to ERR_load_crypto_strings() does nothing and as
ERR_free_strings() doesn't clear this variable again further
calls to ERR_load_crypto_strings() do nothing ...
Cheers,
Nils
