That's a pity. But was this tool geared towards Ada only? There is also "stacktool" written by Dr. John Regehr (CCed) that is for AVR programs, but mainly geared towards TinyOS/AVR based applications. When this first came out, I initially had problems getting it to work on a significantly-sized real-world program. In the end, I never got the tool to work. John and I have had a number of conversations since then about the general problem of doing static analysis on stack usage, and it is a difficult problem to solve.
