Problem when nesting unboxed vectors in user defined data structures with newtype

[kaffeepause73]

when nesting a unboxed vector object in a user defined data structure with newtype using a touple, the show command throws an exception -- but only after an negate command on the user defined data type

Commented code with build and output log and executable in bz2 archive.

Hmm, I'm not convinced this is a problem with vector. Rather, this looks like the culprit to me:

smap f s1 fstr =  Signal (n,t,v,u)
               where 
                 n = getName s1
                 t = getTime s1
                 vdata = getVect s1
                 u = getUnit s1
                 v = V.map f v -- when time data is same

The last line is the what leads to non-termination. Should it be v = V.map f vdata? If not, what behaviour do you expect?

Yes - sorry You are right.

I created an unintended loop (short variable names are nice but dangerous). Sorry for the hassle and thanks for the quick response.
