header_rewrite plugin crashs on Fedora 27

[thelounge-zz]

the same config on Fedora 26 is fine

glibc-2.26-27.fc27.x86_64 versus glibc-2.25-13.fc26.x86_64

[TrafficManager] ==> Cleaning up and reissuing signal #

[thelounge-zz]

since a ton of other services and software (apr, apr-util, mariadb, httpd, mod_security) did run fine with -D_GLIBCXX_ASSERTIONS i obviously copied that to the trafficserver.spec to have it in the next build and did not try the resulting binary until today - this seems to be a security relevant bug in the header_rewrite plugin

gcc-7.3.1-5.fc27.x86_64, same result on Fedora 26 with gcc-7.3.1-2.fc26.x86_64

• Thu Jan 25 2018 Reindl Harald h.reindl@thelounge.net

• add '-D_GLIBCXX_ASSERTIONS' from upcoming Fedora 28 Hardening
  Enable C++ standard library hardening with -D_GLIBCXX_ASSERTIONS
  This turns on cheap range checks for C++ arrays, vectors, and strings

removing -D_GLIBCXX_ASSERTIONS from the flags below (at bottom the fully translated stuff including %{optflags} which are the global ones on that build-environment) and the crashes are gone

Is this still an issue?

[thelounge-zz]
