Description of the Issue
When hashing SHA-256 of large files > ~ 300 MB before first hashing smaller files, NPP will crash.
I repeated with different files, if the first file is above 300 MB, crash will happen.
Steps To Reproduce
- open NPP with no hash previously performed
- go to "Tools -> SHA-256 -> from file"
- click "select file..." , select a file > 300 MB, click ok
- wait for the crash
- do 1. - 3. with file < 300 MB, it will be fine.
- repeat 2. + 3. after 5.: hash will work
Current Behavior
crash, as described above
Expected Behavior
get hash of file

This bug appeared a few versions back (maybe 9 - 12 months ago), but I thought somebody would notice and it would get fixed, so I was patiently waiting. Until now.
