There is a bug within src/lib/posix/getcwd.c!
While scanning back from the current directory to the main
root directory 'getcwd' run's into trouble while reading a
'.' directory when this contains a empty slot.
Commands affected:
- pwd.c
- tar.c
The following patch will overcome this problem:

while (!found && read(fd, (char *)&d, DIRECT_SIZE) == DIRECT_SIZE) {

if (same_device) {
if (current.st_ino == d.d_ino) found = 1;
} else {
