sun's new xvi Ada Xview bindings

[Scott Moody]

Has anyone used the Ada Xview bindings that are comming from
Sun with the new SunAda (previously Verdix Ada) software?

I was trying to write a simple program and it doesn't seem
to be too easy. Especially if you want to debug what goes
wrong since the implementation uses lots of assembly code to
make the calls to the Xview library as seemless as possible.

What is really strange is getting errors
in an initial statement (such as xv_init)
when the next statement is what is really bombing (such as xv_create).

This might be because the stack is getting corrupted, but it
is very strange.

Sample program: (using preprocessor -P and no optimize -O0)

This program bombs if the XV_LABEL is inclosed.
