Looking at this a little more the 0.7 code didn't check
the types in the /_update/ function it simply assigned
the /next/.  I think the changes in 0.8 help support
/Signal/s that contain different objects.  I think the
changes are good (it was a quick look, so I might be off).

The simple change I made was to have the _setNextBool to
always cast to a bool type.  That way we won't have the
/val/ of a /Signal/ changing from one type to another.
Made a similar change with the _setNextInt


This error should block 0.8 from being released.  I will
make a patch and post it with the description.  I have
not resolved the mixing /bool/ and /intbv(0)[1:]/ in the
VHDL conversion.  This should also be fixed and submitted
as a single patch, when I get some more time I will tackle
this next (or if someone resolves the issue :) ).

All the non-conversion unit test in 0.8dev pass with these
changes.  All the general conversion tests pass also with
the exception of two VHDL analyzed with GHDL tests but these
two tests failed before the changes.

Chris
