New Revision: 298626
URL: https://svnweb.freebsd.org/changeset/base/298626

Log:
  Stop using sbrk in csh. This is a legacy interface and its use within csh
  is invalid. It is used to find the size of allocated memory. As malloc may
  allocate memory with mmap it will fail to take this memory into account.
