... the idea behind this (CentOS) bug being to include a modified gcc in centosplus, until RH modifies the version shipped in RHEL

Hmmmm. it looks as if it WAS compiled with -fsanitize support, BUT you can use only one of the listed options at a time. if I use just "-fsanitize=address" it compiles stuff. haven't tested the result yet, nor have I tested "-fsanitize=thread", but I'll get to it.

in the meantime should this bug be closed?

You might want to file a bug to gcc's bugzilla, because "0007463: gcc compiled without support for -fsanitize=address and -fsanitize=thread" is misleading. Tell them you expected both instrumentations to work combined ... ;)
