Alas the Bochs sources I’m using date from 2008.  They made significant changes to the memory interface so that when I looked at upgrading about four or five years ago I took the lazy approach.  I can try and upgrade, and I can also take a look at the gdb source and see if it would work.  But I can’t make promises time wise.

I will take a look at this asap.
