Comment (by Sam James):

 Indeed, hitting this on Linux with both GCC and Clang.

 With Clang 15: https://bugs.gentoo.org/901099
 With GCC 12/13: either this error or a hang (see
 https://bugs.gentoo.org/900937)

 Upstream GCC bug for the hang
 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109137) says this is really
 an issue on the asm side, so the error is legitimate:
 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109137#c5.
