Comment (by kencu):

 gcc on arm64 darwin is currently a project spearheaded by one lone
 developer, and is not yet part of official gcc releases.

 He is very responsive.

 I suggest you open an issue on his github gcc repo here if you want this
 fixed :

 https://github.com/iains/gcc-darwin-arm64/issues

 Now if you are also seeing this reproducibly on an official Intel release,
 he may ask you to open a gcc bug on bugzilla, or may do it humself.
