Looking at the variable locations, I stumbled across another issue. 
After compiling with clang (3.4), I get the following output when asking 
for the locations of the parameters of a function:
f_foo->getParams
    localVar (type, name): s_t, s
    getLocationLists.size: 1
        lowPC: 4195632
        hiPC: 4195675
        ...

This is fine and with that I can later on retrieve the values via 
getLocalVariableValues(). But when I compile it with gcc (4.8.2), the 
output is:
f_foo->getParams
    localVar (type, name): s_t, s
    getLocationLists.size: 0

Due to the emtpy LocationList, getLocalVariableValues() always returns 
-2 (EOutOfScope). Do I miss something here or is this possibly a bug?
Best regards,
Fabian
