Infinite loop in library_status

[Loïc Joly <loic.actarus.joly@…>]

When running library_status from the wrong folder, it go into infinite loop. The following code seems to be responsible (in library_status.cpp, function find_lib_name):

for(count = 0;; ++count){

if(*--e_itr == "libs")

break;

if(lib_test_dir.empty())

throw std::string("must be run from within a library directory");

Why testing lib_test_dir.empty()? Testing e_itr would not work either since operator-- loops when it gets to the start...

fixed.
