1.9.8 sqlselect bug?

[jda]

Ruslan,

I think I may have found a bug in 1.9.8 final (with RB 5.2.1).

I do a search of my database:

   myCursor = myDatabase.SQLSelect(query, kServer, kReadWrite)

I modify the records in the cursor (OK) then nil it:

myCursor = nil

Then I do another search:

   myCursor = myDatabase.SQLSelect(query, kServer, kReadOnly)

This leads to the following crash in OS X:

The weird thing is that this crashes with a large database, but not a 
small one! I've rebuilt the database, reindexed it, and it still 
crashes.

Any ideas?
