afaik, the issue you're observing is due to the message box, which uses t_binbuf internally to (re-)parse messages into pd atoms.

I think, it only happens on saving or reloading of a patch, though.

No, as I noted before it also happens if you edit the message box manually.

For example in the attachement a numeric symbol is generated with [makefilename %d] and written to a message box. While this symbol looks like a number, it is in fact a symbol (as intended) and cannot be used for calculations (but it can be used as text in Gem).

Until you click on the message box in edit mode, and for example add a space (or whatever) at the end, and delete it if you want, to leave the content apparently unchanged. Then the content of the box is reparsed (I guess) and the "123" becomes a real float: if you bang it, the [+] will perform the sum successfully.
