https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D279901 Bug ID: 279901 Summary: glibc-2.39-2 and above on the host segfault Product: Base System Version: 14.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bhyve Assignee: virtualization@FreeBSD.org Reporter: holo@libsharedobject.so Reproduction steps: 1. get current arch iso (or other rolling release linux). The following will deal with archlinux 2. boot install medium inside the bhyve vm, and attempt to run any of: [vim, python3, archinstall, gdb (if installed), localedef] 3. all of the above will crash with a segfault (sigsev) and error 4 (cause = was a user-mode read resulting in no page being found.) 4. downgrading to glibc-2.39-1 fixes all of the above applications, though = in the case of bootstrapping scripts like archinstall, this can be fail to work if, for instance, the script re-downloads glibc.
