Should the same be done for the error log here?

Nit: looking at the implementation of print_ct_warn_log(), it already
seems like it's written to avoid die-ing, so we could avoid the eval
here. Otherwise, I'd add a comment stating that the error from this eval
is ignored on purpose, but again, I don't think we need the eval here.
