--- Comment #6 from Bruno Jesus 00cpxxx@gmail.com --- By the date the bug was posted the newest version was 6.7.2, but comment 2 explicitly says 6.7 - https://notepad-plus-plus.org/repository/6.x/6.7/
And the bug was testes against 1.6.2, but the attachment shows 1.7.33. Comment 0 says that the crash requires computer restart, which indicates the problem may not be in Wine. Also the prefix was shared with something else:
00000014 BackupStack.exe
I have just tested it at 1.6.1 with files of various sizes and could not reproduce the issue.
Is this still an issue in Wine 1.9.24 or later?
