ASAN and libraries can be tricky: https://github.com/google/sanitizers/issues/380 https://github.com/google/sanitizers/issues/111 "When linking shared libraries you should not force asan symbols into .so -- symbols like __asan_* should be left undefined so that at the dynamic-link time they are taken from the main binary." but I don't see which flag (the usual suspects are -Wl,-z,defs or -Wl,--no-undefined) would check the ASAN symbols in graphite2 Oh, looks like something needed a fix in graphite2 build system, 1.3.1 changelog states: . Build now works for clang and/or asan and/or afl etc. Manually building 1.3.4 worked here
@maintainer, could you bump to 1.3.4?
