I think there is a regression. I suspect it is related to 8.7.8 #6, but I haven’t proven that yet. The bug is present in 8.7.8 and 8.7.9, but not in 8.7.7:

Open a new tab and type two lines:

abc
def

Open the Find dialog; turn off wrap around, set regular expression, and enter:
.*
as the find expression. Place the caret at the beginning of the file, then click Find repeatedly. First it finds abc; then a zero length match; then def; then a zero length match.

In 8.7.7, clicking Find a fifth time produces the error message Can’t find the text “.*” from caret to end-of-file. In 8.7.8 and 8.7.9, Notepad++ becomes unresponsive.

Other tests suggest the problem occurs whenever there is a zero length match at the end of the file.

Indeed, it looks like Commit a52738c / PR 16208 is the cause.

Changing the line that changed:

return _document->NextPosition(position, 1);

to

return std::max(_document->NextPosition(position, 1), position + 1);

appears to fix it.

@donho, would you prefer that I prepare another pull request (after further testing)? Submit an issue and a pull request? Leave this to you?

@Coises ,
I can confirm the STR, and it does lock up my portable version of 8.7.9, just as described. There’s no reponse in the find dialog, and the button stays disabled and clicking anywhere else on the dialog crashes the app.
