Description of the Issue

Notepad++ crash when opening very large json file.

Steps to Reproduce the Issue

Apologies for the lack of detail.
61 files open, mostly small text files. Attempted to open a 470MB json file. Cannot share the data file but is valid json..
After some time an Error dialog appeared:

An exception occurred due to plugin: DSpellCheck.dll
Exception reason: bad allocation.

When dismissing the dialog, application crashed.

Attempting to restart application results in a window frame, toolbar and "new 1" being drawn then disappears; app won't start. Windows Error Report (WER) attached.

Removing the offending file entry from session.xml and everything reopens.
Add the line back and crashes again.
Cannot share the data file.

Removing the DSpellCheck plugin results in the file opening (says length 501,626,928, but there's only one line and it's blank. Seems nothing is displayed.

Expected Behavior

Application to open json file., display content.
Standard Notepad opens the file in approx. 1 sec..

Actual Behavior

Application crash
