Well, not exactly. Assuming "x" may contain any 32-bit value
including -2**31, there's not enough room in "str" in the C example to
hold everything. So the true Ada idiom should be something like:
declare
str : constant string := "variable " & name & " =" & integer'image(x);
begin
Write_Trash_All_Over_Your_Stack;
I suspect this is an idiom that would be highly familiar to C
programmers.
