- Triggered by the discussion on how to validate Handles in this group,
- I yesterday loaded the extension "DoubleTrouble" by Greg Marriott, Apple.
- It worked great! I found a serious (and difficult to detect) bug in a
- XFCN I have written in C. Thanks to Greg and Apple for a very useful
- utility! (The DoubleTrouble can be found on the latest Developer CD from
- APDA).
- Today I found another double trouble, this time in the XFCN "ShowList"
- which is distributed with HyperCard 2.1. The stack dump from MacBugs
- reports DisposHandle was called from ShowList + 0010, when DoubleTrouble
- breaks in. Anybode else who have seen this?
