I'm using a 2005/9/3 version of 6.4.1 and running into situations where the "stack trace" has function A calling function B, where when I look at the code, A never calls B. Is this normal? Is it some side-effect of laziness? It sure makes the traces a lot less useful. Frederik -- http://ofb.net/~frederik/
