I think it must be a relatively recent change ... it doesn't show up 
superficially on tests of recent copies of the debugger, and mostly 
I've been using older copies.
My main development systems are using gdb built from cvs with your 
patches on the 7th of March, and the problem
does not show up in your test application with that version of gdb.
