https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=292008 Bug ID: 292008 Summary: armv7 (native and chroot) gets SIGSEGV for: gpart show Product: Base System Version: 16.0-CURRENT Hardware: arm OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: marklmi26-fbsd@yahoo.com Context: official pkgbase distribution installations, both native armv7 boot and armv7 chroot world on aarch64. But the details backtraces differ in the native vs. not examples involved. Also, the freebsd-arm and freebsd-current lists had messages about this before this submittal. armv7 native backtrace (there was no output before the SIGSEGV notice): Core was generated by `gpart show'.
