I propose to apply the following change in base/src/dbStaticLib which
permits non-monotonic breakpoint tables to be loaded after the variable
dbBptNotMonotonic has been explicitly set to a non-zero value. If
you're using iocsh you will also need to add the variable declaration to
the base/src/misc/base.dbd file to be able to set it in an st.cmd file.
I hope this is an acceptable solution.
