Re: Still seeing Failed assertion: "p[i] == 0" on armv7 buildworld [Notes from another example core dump: #4] [New common range #0..#10 __je_pa_alloc]

I'm only sending notes from testing of how similar other failures appear
to the 2 lists. Folks can ask that I do otherwise for them if they want.

This one does not have area_malloc involved at all.

This one is for size 20480 (5 pages). It looks like #0..#10 are similar to
the prior reports. #10 is __je_pa_alloc.

#11 is: __je_arena_extent_alloc_large

For #0..#10: The prior examples and the above
agree about:

#5  __je_extent_alloc_wrapper zero=true

But also there was in this example:
#13 __je_large_malloc         zero=false

(The others before #13 are optimized out.)
