It will be difficult. It's SystemC project, to run it you have to have 
proper SystemC/HDL simulator :( I don't know if you know SystemC (I 
don't ;), see for example http://en.wikipedia.org/wiki/SystemC) It's 
some kind of strongly templated library. My SystemC project is made from 
my library (with debug) which is statically linked with SystemC library 
(without debug) - it's important, because even I have instantiated some 
of SystemC template in my library, gcc often gets symbols from non-debug 
SystemC library and I can't debug such variables (gdb complains 
something about incomplete types).
So I suppose two reasons:
1) I have instantiated template for two specializations (probably - 
SystemC can do it itself) and I try to set breakpoint inside it's 
method. I have problem to get debug information from SystemC library and 
maybe it's the same problem
2) probably simulator loads my library twice using dlopen (or similar), 
and gdb can't access memory for unknown reason

Regardless of this, don't you think it's good idea to adapt MI commands 
for <MULTIPLE> breakpoints? Do you consider it?
