A number of routines (I'm debugging ossl_x509extfactory_create_ext) need to log the entire SSL error call stack in order to provide better diagnostics.
I know how to get this out as a string, but I'm not sure what the best way to return the error is.
I think that we should return an array of strings (it's an error stack), and it's only really ever gonna be meaningful to humans.
Please advise.
