If I do the same thing from the REPL, I get the Slime debugger. I think I should get the Slime debugger in Lisp-mode as well. Obviously calling BREAK directly is not very useful, but when I insert breakpoints in functions by means of calls to BREAK I get the same behaviour. The behaviour depends on where the function is called, not on where it was compiled.
To enforce the Slime debugger you could use swank:simple-break instead of break.
I don't use OpenMCL myself, but after reading the code in swank-openmcl.lisp I'd say that BREAK invokes the Slime debugger only if it is called in the REPL thread. There's even a variable *break-in-sldb* to customize this a bit. We should probably add one more option so that sldb is invoked in all threads. If a OpenMCL user posts a patch for that, I will gladly commit it.
