{{{
Refman Section 2.4.2:
"Variable declarations inside a subroutine must all appear at the
beginning, before the executable statements of the subroutine."
It says it expected to see possibly 'end', since that is
one possible keyword that could legally follow a trace statement
inside a routine.

I thought that was a bug too, but it's just the way Euphoria works.
Routine scoped variables must be declared at the very beginning of a routine
block.
Try this:
with trace
procedure main()
integer i1
trace(1)
i1 = 0
i1 += 1
end procedure
main()
