Re: Still seeing Failed assertion: "p[i] == 0" [ *** i386 chroot on amd64 can get the failure on main 16 too *** ] [failed without new kernel check detection]

I patched the vintage of /usr/src/ on amd64 that is for
the pkgbase vintage that I've been using on the test
machines.

# sysctl debug.vm_check_pg_zero=1
debug.vm_check_pg_zero: 0 -> 1

# env WITH_META_MODE= make -j10 buildworld

I had also previously tested without enabling debug.vm_check_pg_zero
just to check if failures were still happening. It turns out that
for my current context that failed building the same .pico file:
