I've recently run into a lot of problems with tests that link to an excessive number of shared libraries, so I'm glad to see someone working on it. I have a concern with one part, though: On Fri, Sep 9, 2011 at 8:31 AM, Gary Benson wrote: > =A0* when there are no pending breakpoints, If you "break foo", it might put that breakpoint in more than one shared library. If you load a new library with an implementation of foo, we should stop on that one too. How can we make that work without processing the library events? --=20 Thanks, Daniel
