------- Additional Comments From Thomas dot Koenig at online dot de 2005-03-09 16:01 ------- The complaint is a segfault at runtime when you actually want to do anything with the string whose length depends on a missing optional argument. This isn't too bad (the same thing happens if you access a missing optional argument).
