bug#67398: 29.1; ada-mode 8.1.0 -> Restarting the (wisi) parser seems to not fully reset the state

[Jurgen De Backer]

Package: emacs, ada-mode

Hi,

I was editing a file and started to have indentation not working anymore.
Each time I type Tab, I see that the parser died in *Ada-wisi-parser.log*
but no specific message.

(Starting a new emacs on the same file shows no problem.)

Typing Ada -> Misc -> Restart parser
seems to not fully reset the state (because a new fresh emacs does not have a 
problem)

I did C-x C-v to just reload the same file and then all was back to ok.
I found no specific information in a buffer about a parsing problem/crash 
except the process died.

So it looks like restart parser should cleanup more of the internal state of 
the buffer.

But sadly this is not really reproducible.

Thanks

Jurgen De Backer
