Thread local buffers were using pthread_setspecific for storage with lazy initialization. pthread_setspecific shares TLS slots between the linker and libc.so, so thread local buffers being initialized in a different order between libc.so and the linker meant that bad things would happen (manifesting as snprintf not working because the locale was mangled) Bug: http://b/20464031 Test: /data/nativetest64/bionic-unit-tests/bionic-unit-tests everything passes Test: /data/nativetest/bionic-unit-tests/bionic-unit-tests thread_local tests are failing both before and after (KUSER_HELPERS?) Test: /data/nativetest64/bionic-unit-tests-static/bionic-unit-tests-static no additional failures Change-Id: I9f445a77c6e86979f3fa49c4a5feecf6ec2b0c3f
