This should be backported to 1.9 and earlier versions as well.

Also can you try locally jl_gc_alloc

julia/src/gc.c

Line 3181 in 05b99af

JL_DLLEXPORT jl_value_t *(jl_gc_alloc)(jl_ptls_t ptls, size_t sz, void *ty)
directly? It is exported from libjulia-internal.

jl_gc_alloc succeeds, and now pushed code to use that.

I backported this but got an error in the llvmpasses: https://buildkite.com/julialang/julia-release-1-dot-9/builds/101#01866edd-e69e-4681-81ce-5585968bd21b. I'll drop it from the backport branch for now and either @wsmoses and @vchuravy can push a correct backport to those branches.
