If there are two functions with the same name in different directories,
changing the directory does not result in the correct function being called. A
simple example:


a/test.m:
function test()
  printf('correct version\n');
end

b/test.m:
function test()
  printf('incorrect version, changing directory\n');
  cd('../a');
  test();
  cd('../b');
end


Starting in directory 'b' and running 'test()', the expected output (and
output in version 6.1) is:

>> test()
incorrect version, changing directory
correct version


The output in version 7.3 is:

>> test()
incorrect version, changing directory
incorrect version, changing directory
incorrect version, changing directory
...
incorrect version, changing directory
error: max_recursion_depth exceeded
error: called from
    test
    test at line 3 column 3


Adding 'keyboard' to debug the function prevents the error:


b/test.m:
function test()
  printf('incorrect version, changing directory\n');
  cd('../a');
  keyboard;
  test();
  cd('../b');
end

>> test();
incorrect version, changing directory
stopped in test at line 4 [\b\test.m]
4:   keyboard;
keyboard> return;
correct version
