   5 in reverse chronological order of date reported.

   7 * <!Anchor(bug16)>
   8 Bug in the http://www.standardml.org/Basis/real.html#SIG:REAL.fmt:VAL[++Real__<N>__.fmt++], http://www.standardml.org/Basis/real.html#SIG:REAL.fromString:VAL[++Real__<N>__.fromString++], http://www.standardml.org/Basis/real.html#SIG:REAL.scan:VAL[++Real__<N>__.scan++], and http://www.standardml.org/Basis/real.html#SIG:REAL.toString:VAL[++Real__<N>__.toString++] functions of the <:BasisLibrary:Basis Library> implementation.  These functions were using `TO_NEAREST` semantics, but should obey the current rounding mode.  (Only ++Real__<N>__.fmt StringCvt.EXACT++, ++Real__<N>__.fromDecimal++, and ++Real__<N>__.toDecimal++ are specified to override the current rounding mode with `TO_NEAREST` semantics.)

  12 Fixed by revision <!ViewSVNRev(5827)>.

  14 * <!Anchor(bug15)>
  15 Bug in the treatment of floating-point operations.  Floating-point operations depend on the current rounding mode, but were being treated as pure.

  21 * <!Anchor(bug14)>
  22 Bug in the http://www.standardml.org/Basis/real.html#SIG:REAL.toInt:VAL[++Real32.toInt++] function of the <:BasisLibrary:Basis Library> implementation could lead incorrect results when applied to a `Real32.real` value numerically close to `valOf(Int.maxInt)`.

  24 Fixed by revision <!ViewSVNRev(5764)>.
  25
  26 * <!Anchor(bug13)>
  27 The http://www.standardml.org/Basis/socket.html[++Socket++] structure of the <:BasisLibrary:Basis Library> implementation used `andb` rather than `orb` to unmarshal socket options (for ++Socket.Ctl.get__<OPT>__++ functions).
  28 +
  29 Thanks to Anders Petersson for the bug report and patch.
  30 +
  31 Fixed by revision <!ViewSVNRev(5735)>.
  32
  33 * <!Anchor(bug12)>
  34 Bug in the http://www.standardml.org/Basis/date.html[++Date++] structure of the <:BasisLibrary:Basis Library> implementation yielded some functions that would erroneously raise `Date` when applied to a year before 1900.
  35 +
  36 Thanks to Joe Hurd for the bug report.
  37 +
  38 Fixed by revision <!ViewSVNRev(5732)>.

  41 Bug in monomorphisation pass could exhibit the error `Type error: type mismatch`.

  43 Thanks to Vesa Karvonen for the bug report.

  45 Fixed by revision <!ViewSVNRev(5731)>.

  47 * <!Anchor(bug10)>
  48 The http://www.standardml.org/Basis/pack-float.html#SIG:PACK_REAL.toBytes:VAL[++PackReal__<N>__.toBytes++] function in the <:BasisLibrary:Basis Library> implementation incorrectly shared (and mutated) the result vector.

  50 Thanks to Eric McCorkle for the bug report and patch.
  51 +
  52 Fixed by revision <!ViewSVNRev(5281)>.
  53
  54 * <!Anchor(bug09)>
  55 Bug in elaboration of FFI forms.  Using a unary FFI types (e.g., `array`, `ref`, `vector`) in places where `MLton.Pointer.t` was required would lead to an internal error `TypeError`.
  56 +
  57 Fixed by revision <!ViewSVNRev(4890)>.
  58
  59 * <!Anchor(bug08)>
  60 The http://www.standardml.org/Basis/mono-vector.html[++MONO_VECTOR++] signature of the <:BasisLibrary:Basis Library> implementation incorrectly omits the specification of `find`.
  61 +
  62 Fixed by revision <!ViewSVNRev(4707)>.
  63
  64 * <!Anchor(bug07)>
  65 The optimizer reports an internal error (`TypeError`) when an imported C function is called but not used.
  66 +
  67 Thanks to "jq" for the bug report.
  68 +
  69 Fixed by revision <!ViewSVNRev(4690)>.

  71 * <!Anchor(bug06)>
  72 Bug in pass to flatten data structures.

  74 Thanks to Joe Hurd for the bug report.

  78 * <!Anchor(bug05)>
  79 The native codegen's implementation of the C-calling convention failed to widen 16-bit arguments to 32-bits.

  81 Fixed by revision <!ViewSVNRev(4631)>.
  82
  83 * <!Anchor(bug04)>
  84 The http://www.standardml.org/Basis/pack-float.html[++PACK_REAL++] structures of the <:BasisLibrary:Basis Library> implementation used byte, rather than element, indexing.

  86 Fixed by revision <!ViewSVNRev(4411)>.

  89 `MLton.share` could cause a segmentation fault.

  91 Fixed by revision <!ViewSVNRev(4400)>.

  94 The SSA simplifier could eliminate an irredundant test.
  95 +
  96 Fixed by revision <!ViewSVNRev(4370)>.
  97
  98 * <!Anchor(bug01)>
  99 A program with a very large number of functors could exhibit the error `ElaborateEnv.functorClosure: firstTycons`.
