That's very strange. I checked for example for gdb does and it never 
accesses the l_ld field, and assumes every loaded shared module is 
present in the unique ELF module list that we're already scanning.
I could understand that we have some too strict tests somewhere, but I 
don't understand how it could be that we have to call DEBUG_WalkList 
recursively.
So, could look at the entries in the dbg_hdr.r_map list and see whether 
or not the main libraries appear (will some unsupported flags for example).

it actually does, but I'll submit a merged form
