[ Removing lldb-dev from the Cc list as requested. ]
Hi,
First of all, you are repackaging Eclipse CDT and are not distributing
the source code for it; in fact, you have relicensed the entire project
with a proprietary license. Eclipse CDT is license under EPL:
<https://www.eclipse.org/org/documents/epl-v10.php>
Which forbids this practice. EPL still allows you to license your
plugin as proprietary, but you still have to release the source code of
everything else (and if you modified Eclipse CDT in some way, you also
have to release your modifications).
Secondly, what is the advantage of UltraGDB when you compare it with the
Eclipse CDT Standalone Debugger?
<https://wiki.eclipse.org/CDT/StandaloneDebugger>
The Standalone Debugger is Free Software (released under the EPL as
well), and distributed along with the Eclipse CDT on some distributions
(Fedora GNU/Linux, for example). It is nice to see people developing
other plugins and GUI's for GDB (assuming they are Free Software as
well, of course), but it looks to me that Standalone Debugger offers a
better user experience than UltraGDB.
Thank you,

Note that since you are using MI as the interface between your debugger \x10GUI and the debugging backend (gdb) you can try using the lldb-mi layer and test performance between the GDB MI and the LLDB MI. Then you can rename your debugger to be UltraMI to keep your debugger agnostic the the backend debugger. :-)
I noticed in the youtube video that it took 40 seconds to set a breakpoint at lldb's main function and to run to the breakpoint and hit it. If you try LLDB MI, I am guessing it will be faster than 40 seconds.
