If you will rework log_writer() function from your sample to not to print
bytes/symbols after "size" buffer length, than you discover that functionality
not broken in uClibc:

Output is:
size '6'; buffer 'TEST::'
size '4'; buffer 'test'
size '6'; buffer '::TEST'

i.e. complete output will be 'TEST::test::TEST', as expected.

P.S. fopencookie man pages never promise that input buffer "buf" must have '\0'
after "size" bytes.
