[myhdl-list] Lost in conversion ... _error.SignalInMultipleLists

[Josy B. <jos...@gm...>]

While converting a module I get the following:
----
  File "C:\Python27\lib\site-packages\myhdl\conversion\_analyze.py", 
line 147, in _analyzeSigs
    raise ConversionError(_error.SignalInMultipleLists, s._name)
myhdl.ConversionError: Signal in multiple list is not supported: 
pl_ple_2_enables(0)
---
The 'ofending' section in _analyze.py:
---
    # handle the case where a named signal appears in a list also by 
giving
    # priority to the list and marking the signals as unused
    print '_analyzeSigs - memlist',memlist
    for m in memlist:
        if not m._used:
            continue
#         print m
        for i, s in enumerate(m.mem):
            s._name = "%s%s%s%s" % (m.name, open, i, close)
            print m.name, s._name, s._inList,
            s._used = False
            if s._inList:
                raise ConversionError(_error.SignalInMultipleLists, 
s._name)
            s._inList = True
            if not s._nrbits:
                raise ConversionError(_error.UndefinedBitWidth, s._name)
            if type(s.val) != type(m.elObj.val):
                raise ConversionError(_error.InconsistentType, s._name)
            if s._nrbits != m.elObj._nrbits:
                raise ConversionError(_error.InconsistentBitWidth, 
s._name)
            print'->', s._name, s._inList
----
I added some print statements to _analyze.py as you can see.
The exception is raised when _inList is already set. _inList is however 
initialised to False in _Signal.py and only set to True in the above 
code.
Here is the output of these 2 print statemants:
---
pl_Enables pl_Enables(0) False -> pl_Enables(0) True
pl_Enables pl_Enables(1) False -> pl_Enables(1) True
pl_Enables pl_Enables(2) False -> pl_Enables(2) True
pl_ple_2_lenables pl_ple_2_lenables(0) False -> pl_ple_2_lenables(0) 
True
pl_ple_2_readies pl_ple_2_readies(0) False -> pl_ple_2_readies(0) True
pl_ple_2_enables pl_ple_2_enables(0) True
---
Can somebody shed some light?
