Hi When trying to translate the latest version of PyPy on FreeBSD I get the following error: [translation:info] Error: File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/translator/goal/translate.py", line 318, in main drv.proceed(goals) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/translator/driver.py", line 554, in proceed result = self._execute(goals, task_skip = self._maybe_skip()) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/translator/tool/taskengine.py", line 114, in _execute res = self._do(goal, taskcallable, *args, **kwds) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/translator/driver.py", line 278, in _do res = func() File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/translator/driver.py", line 315, in task_annotate s = annotator.build_types(self.entry_point, self.inputtypes) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/annotator/annrpython.py", line 92, in build_types return self.build_graph_types(flowgraph, inputs_s, complete_now=complete_now) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/annotator/annrpython.py", line 140, in build_graph_types self.complete() File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/annotator/annrpython.py", line 229, in complete self.complete_pending_blocks() File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/annotator/annrpython.py", line 224, in complete_pending_blocks self.processblock(graph, block) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/annotator/annrpython.py", line 398, in processblock self.flowin(graph, block) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/annotator/annrpython.py", line 501, in flowin self.consider_op(op) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/annotator/annrpython.py", line 653, in consider_op resultcell = op.consider(self) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/flowspace/operation.py", line 104, in consider return spec(annotator, *self.args) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/annotator/unaryop.py", line 118, in simple_call_SomeObject return s_func.call(argspec) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/annotator/unaryop.py", line 978, in call return bookkeeper.pbc_call(self, args) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/annotator/bookkeeper.py", line 535, in pbc_call results.append(desc.pycall(whence, args, s_previous_result, op)) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/annotator/description.py", line 398, in pycall s_result = self.specialize(inputcells, op) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/annotator/description.py", line 281, in specialize return self.specializer(self, inputcells) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/annotator/specialize.py", line 303, in memo _, _, memotable = memotables.find(firstvalues) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/tool/algo/unionfind.py", line 48, in find info = self.info_factory(obj) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/annotator/specialize.py", line 293, in compute_one_result value = func(*args) File "/home/dbn/ports/ports/lang/pypy/work/pypy2-v6.0.0-src/rpython/rlib/rarithmetic.py", line 154, in _should_widen_type r_class = rffi.platform.numbertype_to_rclass[tp] [translation:ERROR] KeyError: <Void> Processing block: block@28[n_1] is a <class 'rpython.flowspace.flowcontext.SpamBlock'> in (rpython.rlib.rarithmetic:139)widen__NoneType containing the following operations: v630 = simple_call((function typeOf), n_1) v631 = simple_call((function _should_widen_type), v630) v632 = bool(v631) --end-- My best guess is a call to `widen` with a None value is being specialized.
