I believe this is a long standing bug in plsql-mode. I submitted a
patch to fix this to the author about 4+ years ago, but have never
seen it implemented/updated. Essentially, I don't think there is any
currently maintained plsql-mode. 

I would give you my patch, but I stopped working with Oracle not long
after that and don't seem to have it in my archives. However, I do
remember it was relatively easy to fix. 

Enable debug on error in emacs and you should be able to track down
the problem quite easily. From memory (which could be completely
wrong), there was an error in one of the regular expressions.

Note that there are a few different plsql  modes out there - I think
initially, I tracked down more than four. However, none of them were
being actively maintained and all of them had problems. The one I was
using I found on the emacs wiki site.
