I think I resolved the issue. It has to do with how Arrow reads Tables from
disk. It does not load the entire table into memory but uses only a view. If
you write this view to the *same* file, it causes this bus error.
```
using TypedTables
using Arrow
tab = Table(
a=[i for i=1:10],
b=[fill(0.1,10) for i=1:10]
)
filename = "test.arrow"
Arrow.write(filename, tab; file=false)
newtab = Table(Arrow.Table(filename))
Arrow.write(filename, deepcopy(newtab)) # always works
Arrow.write(filename, copy(newtab)) # only works for simple columns like :a,
but not :b
Arrow.write(filename, newtab) # always fails
```
I wonder if this is also the case in @simsurace's error.
