To follow up on this, and why I provided you with a new patch, from
getcwd's man page:
char *getcwd(char *buf, size_t size);
On OpenBSD and FreeBSD, it says this:
If buf is NULL, space is allocated as necessary to store the
pathname. This space may later be free(3)'d.
On Solaris:
If buf is a null pointer, getcwd() will obtain size bytes of
space using malloc(3C). In this case, the pointer returned by
getcwd() may be used as the argument in a subsequent call to
free().
On Linux, it says this:
If buf is NULL, the behaviour of getcwd() is undefined.
Perhaps the best way is to use NULL in the first argument for the BSD
family, and get_current_working_dir in Linux. Setting the buffer size hard
to 4k is a workaround solution, but it's one that works for all for now.
