> EFTH MINIX report #38  - August 1988 -  getcwd(3)

My implementation of getcwd(3) has a bug. Thanks to
Earl Chew for funding it. (Is there a prize for finding
the first V1.4 bug?) The problem arises because getcwd(3)
does not reset the current directory before returning.

Earl supplied the following fix to set the directory
on NON-ERROR returns. Just change the last return() on
line 157 to:
  
  return( chdir( buffer ) ? NULL : buffer );
