            Bug ID: 256468
           Summary: reaching a breakpoint on an armv7 binary on arm64
                    causes a SIGBUS
           Product: Base System
           Version: 13.0-RELEASE
          Hardware: arm64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: arm
          Assignee: [email protected]

It appears that debugging armv7 binaries on arm64 is broken.

I've created an armv7 jail on an arm64 FreeBSD 13.0-RELEASE system, entered it,
and install gdb from ports.  Then I executed an arbitrary program under gdb,
set a breakpoint and let the program run (a simple way to do this is to type
"start").  The breakpoint is reached and gdb informs me that a SIGBUS was
delivered to the program; attempting to continue after this breakpoint is
impossible.

I suppose there's something wrong here as debugging on a native armv7 system
seems to work fine.
