I've tried Emacs 24.5 and emacs-25 branch, on Windows/MinGW64 and Debian
on VMWare/Windows.

I'm testing with:

(+ "foo" 2)

evaluated in the scratch buffer with C-j. Same result evaluating via M-:.

It does for me.

With just "emacs", the above puts an error message in *Messages* if
`debug-on-error' is nil.

With "emacs -Q", it opens the *Backtraces* buffer independent of
`debug-on-error'.


I found a workaround; eval the expression once to get *Backtraces*.
Then eval it again without quiting the debugger; that gives the error
message.
