What this means is that Thread 1 gets NULL instead of a list as its
on-stack argument (vm-engine.c:909 is ‘tail-apply’).
How can arguments on the VM stack be zeroed?
I commented out the MADV_DONTNEED call to be sure, but I can still
reproduce the bug.
Then I thought vp->sp might be out-of-sync compared to the local
variable ‘sp’, which in turn could cause ‘scm_i_vm_mark_stack’ to not
mark a few items on the tip of the stack. So I did this:

That seemed to help but I eventually got another similar crash.
FWIW I managed to reduce (guix build graft) to just the code below, and
it’s enough to trigger a crash after a dozen of runs:

Thoughts? Whatever ideas you have could be helpful. :-)
