New Revision: 216809
URL: http://svn.freebsd.org/changeset/base/216809

Log:
  printf: Do not use sh memory functions in sh builtin.
  
  These functions throw exceptions if they fail, possibly causing memory
  leaks. The normal out-of-memory handling suffices. The INTOFF around almost
  all of printf prevents memory leaks due to SIGINT.

  head/usr.bin/printf/printf.c
