buffer renamed "expand(" on save

This issue has plagued me for years in MacVim and I have not been able to identify the source. It is intermittent, and occurs roughly 1 every 100 hundred saves (so probably 2 or 3 times per day). I cannot say what triggers it but I have not been able to make it go away. Any advice or fix gratefully received.

What happens:

• I hit <D-s> to save current buffer, which is already associated with a filename
• the buffer is not saved
• current buffer is magically renamed expand(, the contents are unaffected
• editing continues as normal (If I try to save again, then a new file called expand( is saved to disk).

Environment

• Vim version 8.2
• MacOS 11.6
• Terminal: GUI

Commencez par reproduire le comportement intermittent lors de l’enregistrement dans MacVim avec Vim 8.2 sur macOS 11.6 en utilisant sur un buffer nommé. Examinez le chemin d’enregistrement et la gestion de l’interface graphique autour du renommage du buffer en expand(. Le travail est terminé lorsque le buffer d’origine reste associé à son nom de fichier et s’enregistre correctement lorsque le problème est déclenché.
