Timothy (Dec 14 2022 at 09:28): Timothy (Dec 14 2022 at 09:28):I'm trying to use a TypedTables.Table instead of a DataFrame to make memory usage smoother in a threaded function of mine, however, I'm running into a segfault issue.

For reference, Table.jl:139 refers to the second last line of the following function (just before end)
@inline function Base.getindex(t::Table{T}, i::Int...) where {T}
@boundscheck checkbounds(t, i...)
convert(T, map(col -> @inbounds(getindex(col, i...)), columns(t)))::T
end
you only checked the bounds of all i against t, not against the columns of t
Sukera (Dec 14 2022 at 10:13):presumably you only want to use the nth i on the nth column?
Sukera (Dec 14 2022 at 10:14):sounds like a bug in TypedTables
Alexander (Dec 14 2022 at 15:23):Do you have a code example, of how this getindex is actually called? What are table columns - regular arrays?
