I updated a powerpc64 be system from fedora 25 (glibc 2.24) to fedora 26 (glibc 2.25) and several test cases started failing that deal with dynamic thread local storage.
Failing Tests (3):
LeakSanitizer-AddressSanitizer-powerpc64 :: TestCases/Linux/use_tls_dynamic.cc
LeakSanitizer-Standalone-powerpc64 :: TestCases/Linux/use_tls_dynamic.cc
MemorySanitizer-POWERPC64 :: dtls_test.c
I looked at dtls_test.c in detail
******************** TEST 'MemorySanitizer-POWERPC64 :: dtls_test.c' FAILED ********************
