--- Comment #1 from Vincent Lefèvre <vincent-gcc at vinc17 dot net> --- I detected the issue on tests/tfpif.c with the upgrade of Debian's package gcc-snapshot from 1:20220126-1 to 1:20220630-1 (it doesn't occur on tests/tfpif.c with gcc-snapshot 1:20220126-1). However, the simplified testcase I've provided fails with gcc-snapshot 1:20220126-1.
