I was able to build and install (well, I did it several times until it 
succeeded :-)).
It's not clear which compiler can be used but with GCC 12.1 it worked.

I had problems in the past to build wisi-3.1.7 on Ubuntu 20.04 with gnat-9.
I also had problems with compiling with GNAT community 2021 so I switch to gcc 
12...
May be you can add a note about which compiler must be used?

I've noted that `ada_mode_wisi_lr1_parse` is consuming more and more memory.
It's not a regression since I've observed that with ada-mode-7.1.3.

I have the habit of never stopping/killing emacs to keep my buffers and other 
context.
After 2 or 3 days of editing, I regularly get a wisi parser that uses more than 
1G of RSS memory.
(one day up to 8G)

I don't use any feature of the ada-mode except the auto-indentation while 
writing code.

Is there anything I can do to help you spot this issue?

Best regards,
