This won't be the cause of the crash, but: don't run ninja directly. The
build instructions (documented in README.rst) haven't changed: run
configure, and then run make. The makefile still does some things and is
not a pure does-absolutely-nothing wrapper around ninja in all cases.

I'm able to reproduce a coredump o("Illegal Instruction", but of host
type) during a debootstrap process. The coredump is for a grep process,
I'm trying to bisect.

commit 26bab757d41b853ea84cb52a10fafc9c10069658
Author: Richard Henderson <richard.henderson@linaro.org>
Date:   Fri Feb 12 10:48:33 2021 -0800

    linux-user: Introduce PAGE_ANON
    
    Record whether the backing page is anonymous, or if it has file
    backing.  This will allow us to get close to the Linux AArch64
    ABI for MTE, which allows tag memory only on ram-backed VMAs.
    
    The real ABI allows tag memory on files, when those files are
    on ram-backed filesystems, such as tmpfs.  We will not be able
    to implement that in QEMU linux-user.
    
    Thankfully, anonymous memory for malloc arenas is the primary
    consumer of this feature, so this restricted version should
    still be of use.

The fix that Phil links would only pertain if debootstrap were
actively using MTE.  I think we can safely disregard that.

I don't believe that the bisect has worked.  There is nothing in
that 3 line patch that would affect *anything*, as the PAGE_ANON
value is not used at this point.

Yes, applying the patch pointed out by Philippe doesn't fix the problem.

But I think bisect has worked fine.

If I revert this patch (26bab757d41), it works fine again.

I revert:

"target/arm: Add allocation tag storage for user mode"
 "linux-user: Introduce PAGE_ANON"

Only reverting the first patch doesn't fix the problem.

Perhaps the reason is:

#define PAGE_ANON      0x0080

  This prevents me from building an arm64 Debian image on x86_64. If I
  am doing something wrong, please let me know. The binary has been
