John Reiser says "g++" in a reply not cc:-ed to the bug:
http://thread.gmane.org/gmane.linux.debian.ports.arm/8422/focus=8424
I think he's right, so cloning the bug and assigning the copy to g++.
I'm OK with adding "-g" to xapian-bindings' debian/rules as a workaround, so
keeping 576944 to track that (have committed this change, will include in
1.0.19-1).
Cheers,
