I'm experiencing a reproducible crash when trying to edit a Javascript file.
GDB and the bug reporting wizard are having problems generating a stack tra=
ce.
Valgrind reports:

To reproduce:

- Open
https://raw.githubusercontent.com/Kitware/vaui/84ba21ecce5fb64388b1510b50c8=
cbb8c9bda3e1/web_external/Viewer/ImageViewerWidgetWrapper/VauiGeoJSImageVie=
wer.js
- Move the caret to the end of line 36 (`var pendingNext =3D false;`)
- Press enter

Curiously, if I paste the file contents into an empty document and set HL to
'javascript', no crash...
