Hmm, I'd thought that you should know :-) Since you did the (quite large)
modifications of my execve implementation, and the original had this comment:
* I think this should be vastly more machine dependent
* (e.g. stack up/down, startup stack format etc.)
I.e. the current version of our code to setup the stack of a new process
image only supports machines where the stack grows down.
Yes, I do consider this a bug (see the comment cited above). Yes, I intend
to fix it at some time (together with some other machine dependencies in our
current execve implementation).
