Ticket #881:
Translation fails: bit ops, division, sequence initialization
-

Two tiny programs.
The first:
function foo(integer x)
return and_bits(floor(x/{#40,#08,#1}), #7)
end function
constant b = #AA
sequence s0 = foo(b)
The second:
function foo(integer x)
return and_bits(x, {#C0,#38,#7})/{#40,#08,#1}
end function
constant b = #AA
sequence s0 = foo(b)
Both programs are failed to be translated. The translator just outputs something like `Build directory: build-335365\` and then silently closes itself. Also it emits two empty .c files in that directory.
Command line:
euc -gcc -con -keep test.exw

If you are coming across this in production code try the line
without inline
at the top of the file.

Okay, I have a fix for this. Just a day or two from now, I'll send it out.
