[Casa-framework] ::casac::variant as output parameter crashes casapy

[Raymond Rusk]

Hi Darrell,

I have added a trivial 'void image::outputvariant(::casac::variant& v)' 
method which illustrates the problem as simply as I know how.  The method 
puts a value into the single variant output parameter and then prints "all 
is well so far" just before it returns.  Executed from casapy I see:

CASA <1>: x=ia.outputvariant()
all is well so far
./run: line 6: 16211 Segmentation fault      casapy
