I think the only thing crazy about it is to set pop-up-frames to t while
keeping display-buffer-reuse-frames to nil. Such a setup will
lead to the
above problem in many more situations than just the debugger.
Maybe display-buffer-reuse-frames should simply default to t,
or at least
default to t whenever pop-up-frames is non-nil.
I get the same bugged behavior (in Emacs -q) when these are both `t':
pop-up-frames
display-buffer-reuse-frames
In fact, it is in such a setup that I first discovered the bug.
Perhaps this problem has been fixed since the version I'm using? In my
version, a new frame is created with each debug step.
In GNU Emacs 22.0.50.2 (i386-mingw-nt5.1.2600)
of 2005-04-16 on LAPTOP
Distributor `Microsoft Corp.', version 5.1.2600
configured using `configure --with-gcc (3.4)'
And, yes, I think the default value for `display-buffer-reuse-frames' should
be `t'. People upgrading from versions of Emacs that don't have this
variable will expect more or less unchanged behavior without having to
explicitly set this variable to `t'.
