********
  A compiler problem that allowed the generation of ev67 instructions
  (ctpop, ctlz, cttz) to be generated when using the -arch ev6 switch.

PROBLEM:  (CXXC_BUGS 6746)    (Patch ID: OSF440-134)
********
  A compile time performance problem with a very large (1.6 MB)
  initialization of an array.

PROBLEM:  (DECC 2745, GEM_BUGS 7619)    (Patch ID: OSF440-134)
********
  An optimizer problem that caused an incorrect result when using
  a signed char in a strcpy-like routine, if compiled -O4 or higher.

PROBLEM:  (DIGITAL_UNIX 5109, CXXC_BUGS 6415/6288) (Patch ID: OSF440-134)
********

********

  o A compiler crash when compiling Xemacs 21.1.4 with -O4

  o An optimizer problem in loop unrolling that suppressed intermediate
   updates to induction variables under certain conditions.

  o A particular short parameter assignment caused incorrect
    run-time result

  o An assignment of type k = (char)(l >> 8) was not sign-extended

  o An optimizer problem that produced incorrect code when certain
    bounds checking within a loop was moved outside the loop.
