As far as I know BLR code does not contain line numbers for debugging,
so engine cannot return you such information.

I remember, there was a bug, that creating a database with default
character set did not cause automatic character set assignment for
character columns/params. However I do not remember to which engine is
this related (probably it was introduced in some RC and fixed in one
of the next RCs).
