I don't know but I left a few guesses in [this comment](https://bugs.openjdk.java.net/browse/JDK-8282607?focusedCommentId=14495313&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14495313):
* Is register x14 special on macosx-aarch64?
* Could this be a missing WX transition in hs-err dumping?
* Or some unsafe memory access in [os::print_location](https://github.com/openjdk/jdk/blob/73c5e993e17f7435553edae79a1e8d70ece5493d/src/hotspot/share/runtime/os.cpp#L1072)?

I haven't seen any instances of it failing on bsd so would prefer to keep the workaround specific to macOS.
