bug#47366: 27.1; Tags search (regexp): FAILS

[Bob Floyd]

Hi,

 

When I do a “tags-search FooFoo” sometimes the search stops in a buffer at the wrong line. FooFoo is indeed in the buffer, but can be many lines away from where emacs stopped. If I “kill-buffer” (C-x k) and restart the “tags-search” then emacs stops at the correct line where FooFoo is. I think this happens when I do a “tags-search”, make edits in the buffer, then “save-some-buffers” (C-x s) followed by a 2^nd “tags-search” that then fails.

 

It appears maybe that the regex compiler isn’t run after the edits?

 

Sorry I can’t provide an exact sequence of commands for you to see it, it doesn’t happen always (maybe it doesn’t even stop in the buffer and I don’t notice), but perhaps you can recognize the issue.

 

Thanks,

Bob Floyd
