Here are the known bugs in MLton 20051202, listed in reverse chronological order of date reported.
-
Bug in the Real<N>.fmt, Real<N>.fromString, Real<N>.scan, and Real<N>.toString functions of the 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.)
Thanks to Sean McLaughlin for the bug report.
Fixed by revision r5827.
-
Bug in the treatment of floating-point operations. Floating-point operations depend on the current rounding mode, but were being treated as pure.
Thanks to Sean McLaughlin for the bug report.
Fixed by revision r5794.
-
Bug in the Real32.toInt function of the Basis Library implementation could lead incorrect results when applied to a Real32.real value numerically close to valOf(Int.maxInt).
Fixed by revision r5764.
-
The Socket structure of the Basis Library implementation used andb rather than orb to unmarshal socket options (for Socket.Ctl.get<OPT> functions).
Thanks to Anders Petersson for the bug report and patch.
Fixed by revision r5735.
-
Bug in the Date structure of the Basis Library implementation yielded some functions that would erroneously raise Date when applied to a year before 1900.
Thanks to Joe Hurd for the bug report.
Fixed by revision r5732.
-
Bug in monomorphisation pass could exhibit the error Type error: type mismatch.
Thanks to Vesa Karvonen for the bug report.
Fixed by revision r5731.
-
The PackReal<N>.toBytes function in the Basis Library implementation incorrectly shared (and mutated) the result vector.
Thanks to Eric McCorkle for the bug report and patch.
Fixed by revision r5281.
-
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.
Fixed by revision r4890.
-
The MONO_VECTOR signature of the Basis Library implementation incorrectly omits the specification of find.
Fixed by revision r4707.
-
The optimizer reports an internal error (TypeError) when an imported C function is called but not used.
Thanks to "jq" for the bug report.
Fixed by revision r4690.
-
Bug in pass to flatten data structures.
Thanks to Joe Hurd for the bug report.
Fixed by revision r4662.
-
The native codegen’s implementation of the C-calling convention failed to widen 16-bit arguments to 32-bits.
Fixed by revision r4631.
-
The PACK_REAL structures of the Basis Library implementation used byte, rather than element, indexing.
Fixed by revision r4411.
-
MLton.share could cause a segmentation fault.
Fixed by revision r4400.
-
The SSA simplifier could eliminate an irredundant test.
Fixed by revision r4370.
-
A program with a very large number of functors could exhibit the error ElaborateEnv.functorClosure: firstTycons.
Fixed by revision r4344.
