My clang 5.0.1 produces a test that displays the monkeys correctly, but does not count their width properly:Is this a different bug though ? The issue with iswprint() is varying according to glibc version, not compiler version.
The broken setup is: sys-libs/glibc-2.25-r9 sys-devel/clang-5.0.1 It works on: sys-libs/glibc-2.26-r7 with either of: sys-devel/clang-5.0.1 sys-devel/clang-6.0.1 So yes, it is a glibc bug. Depending on the version, either just wcwidth returns incorrect values for the monkeys (my case) or iswprint considers them non-printable.
So I wonder if the clang problem you mention is something that can be fixed in some way ?
Nope, red herring. My maint point was that there are more than 2 possible results. Jano
