StackOverflowError with CSV.File when using HybridArrays and Symbolics in 1.7 #43357
Description
I'm comming from Discourse.
I experience a 'StackOverflowError()' when running this
using CSV, Symbolics, HybridArrays
function test1()
CSV.File(IOBuffer("Number\n2.0"); delim = "; ", types = Float64)
end
function test2()
CSV.File(""; delim = "; ", types = Float64)
end
test1()
test2()
Both, test1 and test2 throw the 'StackOverflowError()', many of these are printed:
intersect_aside at /cygdrive/c/buildbot/worker/package_win64/build/src\subtype.c:2131
intersect_var at /cygdrive/c/buildbot/worker/package_win64/build/src\subtype.c:2334
intersect at /cygdrive/c/buildbot/worker/package_win64/build/src\subtype.c:3053
intersect_union at /cygdrive/c/buildbot/worker/package_win64/build/src\subtype.c:2154

intersect_all at /cygdrive/c/buildbot/worker/package_win64/build/src\subtype.c:3196
and then the right results appears as well. However I had also cases where julia stoped working.
The problem only appears when using Symbolics, HybridArrays.
In 1.6.4 everything works as expected.
#43050 looks related but there 1.6.3 error'd as well.
I've seen this for different systems:
