Code generated for testcase

See the code generated for this testcase (with my recent patch for improved
out-of-bounds messages). In order to create a temporary, we first run the i=1:1
loop once, without the conditionnal mask (which in this case is .false.), to
count the total length needed for the temporary (variable num.5). When doing
this, we perform bounds checking on elements that will not be used in the final
loop.
