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

Inizia riproducendo il comportamento intermittente durante il salvataggio in MacVim con Vim 8.2 su macOS 11.6 usando su un buffer denominato. Analizza il percorso di salvataggio e la gestione della GUI in relazione alla ridenominazione del buffer in expand(. Il lavoro è completato quando il buffer originale rimane associato al proprio nome file e viene salvato correttamente quando il problema viene attivato.
