Some inference and allocation test failures in Julia v1.12+

[giordano]

These tests

FixedSizeArrays.jl/test/runtests.jl

Lines 149 to 150 in 91d43bf

	test_inferred(collect_as, return_type, (FixedSizeArray{Int}, iter))
	test_inferred(collect_as, return_type, (FixedSizeVector{Int}, iter))

fail in Julia v1.12 and v1.13

Also in both v1.12 and v1.13 this one

FixedSizeArrays.jl/test/runtests.jl

Line 544 in 91d43bf

test_inferred_noalloc(reshape, T, (a, shape2...))

fails the no allocations.

Finally,

FixedSizeArrays.jl/test/runtests.jl

Line 624 in 91d43bf

test_inferred(collect_as, FSA{E,dim_count}, (T, iterator))

FixedSizeArrays.jl/test/runtests.jl

Line 638 in 91d43bf

test_inferred(collect_as, FSA{Float64,dim_count}, (T, iterator))

fail only in julia v1.12, and only for some iterators.

@nsajko I believe you introduced all these tests, would you please be able to have a look? It's probable these are upstream issues in Julia, but it'd be good to reduce them and report them. Also, most of these issues are related to the use of Collects.jl. In the meantime I'm marking them as broken in #159.

It's more likely that this is the minor change in how @allocated works. The tests likely need some rejiggering

[giordano]

Not all of them are about allocations though, some are inference.
