So we can: - leave this as-is for gcc-14 (known bug) - commit what we discussed in #c15 #c16, (with an improved testcase as you mentioned on the list,) thus at least temporarily forcing canonicalization (preventing users from using 'weird' values) - possibly revisit this for gcc-15 by handling predicates differently=
