Description James Blackburn

This may be a dupe, but seems a major out-of-the box regression from CDI.

I've got a bunch of breakpoints in some source files that exist in a .so. CDI correctly sets these when it detects the .so is loaded, while DSF doesn't. The result is I haven't figure out (out the box anyway) how to use DSF to debug my app.

GNU gdb (GDB) 7.0.1

Sorry James, this is one of the parity bugs we didn't have time to get too.  The fix (GDB >= 6.8) is not very big, but the handling of the breakpoint marker was not trivial and I ran out of time.

If you want to try a hack to make your life easier, you can make the below two character change in     
org.eclipse.cdt.dsf.mi.service.command.commands.MIBreakInsert
I think this will make your breakpoints on shared libs work.

   public MIBreakInsert(IBreakpointsTargetDMContext ctx, boolean isTemporary,
                        boolean isHardware, String condition, int ignoreCount, 
                        String location, int tid, boolean disabled, 
                        boolean isTracepoint) {

-               super(ctx, "-break-insert"); //$NON-NLS-1$
+               super(ctx, "-break-insert -f"); //$NON-NLS-1$
