Comment 8 Tor Rune Skoglund 2019-01-22 16:16:23 UTC
This issue is probably not related to gcc itself, but the linux-headers used when compiling util-vserver. 

At least when compiling util-vserver with linux-headers 4.14 on a vserver kernel 4.9, the problem appears. When installing linux-headers that match the running kernel version, i.e. linux-headers-4.9, the problem goes away on my systems, with both gcc 6.4 and gcc 7.3.
Comment 9 Tor Rune Skoglund 2019-01-24 17:11:28 UTC
Actually, based on this debian bug report, it seems to be a dietlibc shortcoming: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=885961
