The proposed fix tries to load numa_node_to_cpus() version 1.2 first. The fix is included into the Portola patch. See discussion on the portola-dev alias: https://mail.openjdk.java.net/pipermail/portola-dev/2020-July/000465.html Proposed changes (including other changes related to Portola patch): https://cr.openjdk.java.net/~avoitylov/webrev.8247589.01/src/hotspot/os/linux/os_linux.hpp.udiff.html https://cr.openjdk.java.net/~avoitylov/webrev.8247589.01/src/hotspot/os/linux/os_linux.cpp.udiff.html

musl libc is not able to load symbols with version. See discussion on musl alias: https://www.openwall.com/lists/musl/2020/05/26/2 jdk loads numa_node_to_cpus function with version libnuma_1.1 which has 3 parameters: numa_node_to_cpus(int node, unsigned long *buffer, int bufferlen) musl libc loads the latest numa_node_to_cpus function version 1.2 with 2 parameters: numa_node_to_cpus(int node, struct bitmask *mask); Using numa_node_to_cpus function with unexpected parameters leads to the test crash.
