Hi Salvo,

test_app is defined as follows :

#define test_app "test1"

so

if (test_app[0] == '/')

was a typo and segfaulting in uClibc.

The test (app) could have been invoked either from 1) <test path> or 2) 
from another path :
  - 1) test_path for test_app is pwd/test_app (not pwd/basename(test_path))
  - 2) test_path is dirname(app)/test_app (not test_app)

Furthermore change related to argv variable is mostly a tidy-up plus 
again drop of
basename(test_app).

Hope it's clear enough ;-)

Hi Salvo,
could you re-elaborate the patch description, and post it again.
Great catch anyway !

Ok, I minimized changes (left basename as is), arranged description
and sent the (new) patch.
