Extended Description

Created an attachment (id=940)
source code to reproduce fault
I just stumbled onto a problem with LACSO and LACSI, wherein they
scramble scalar result values coming in/out of CONDFUNs. 
Since both optimizations are currently disabled, this is not a big problem,
but it was a wee bit puzzling to figure out.
sac2c -V
sac2c v1.00-beta (Haggis And Apple)
 developer rev 18033 linux-gnu_x86_64

sac2c -v1 crudshift.sac -dolacsi -dolacso -nols
prints a vector of all 42s, which is certainly wrong
for "shift(2, 42, iota(50))". 
It works properly if you compile without the above options.
