Two questions, this works fine for me: `UBSAN_CFLAGS="-fsanitize=undefined -fsanitize=float-divide-by-zero -Wno-stringop-truncation -Wno-format-overflow -fno-omit-frame-pointer" ; UBSAN_LDFLAGS="-fsanitize=undefined -fsanitize=float-divide-by-zero" ; sh configure --with-conf-name=udf --with-debug-level=fastdebug --with-native-debug-symbols=internal -with-version-opt=releaserobbin --with-gtest=/home/rehn/source/gtest181/ --disable-precompiled-headers --enable-dtrace --with-extra-cflags="$UBSAN_CFLAGS" --with-extra-cxxflags="$UBSAN_CFLAGS" --with-extra-ldflags="$UBSAN_LDFLAGS" && make images CONF=udf` I.e.build works ? Secondly, the method __ubsan_default_options is in the java launcher. libjvm.so is a "standalone product" that can be used by different launchers. So I'm not sure it should be in launcher if it was needed. ------------- PR: https://git.openjdk.org/jdk/pull/11604
