Thanks for letting me know.  Is this in gdb or lldb?  lldb shows me alignof(struct Lisp_Vector) == 4 on a similar Debian system, which looks wrong to me.  I've fixed things on that system for now (it was building without mps, because that requires -pthread in the CFLAGS to link on that machine...)

Can you try the attached patch?
