Xapian discuss - Jan 2008 - Core dupmed error in Xapian::WritableDatabase::delete_document (const std::string &unique_term)

Hello, I found this bug many times. When I call the delete_document() and pass
the term parameter to delete some matched documents from the exists Xapian
Database, It caught the some error, the following is the orignal error message
on the screen:

---

terminate called after throwing an instance of 'std::bad_alloc'
  what():  St9bad_alloc
Abort trap: 6 (core dumped)

----
But once delete_document() call matched fewer documents, It have not errors. So
I guess that when delete many documents(about 10,000 or more) by a term, the
Xapian will be terminated. :(

Is there a code bug? How can I solve this problem? thanks

This probably means you're running out of memory.  Are you low on
memory?

Otherwise, I guess heap corruption could cause this.  What platform are
you on?  If valgrind is available, can you run your program under it
to see if it reports anything.

I don't really see why this would consume a lot of memory.
