+description = """Several wide-string functions from glibc are broken und qemu user emulation.
+Affected are at least: `wcsbrk()`, `wcsspn()` and `wcscspn()`. All of these are implemented in optimized assembler in glibc.
+
+Unfortunately I don't have access to the real hardware to check the behavior there. But it would probably been detected by now.
+Also I don't know which instructions exactly don't work, as I don't have any knowledge about s390x assembler."""
