Attempt to reproduce https://github.com/RoaringBitmap/CRoaring/issues/819

	# Reproducer for the v4.6.1 roaring_bitmap_to_uint32_array wasm report.
	#
	# Fetches the official v4.6.1 amalgamation release assets, builds the
	# reproducer for wasm32-wasi (using the flags from the bug report) and for the
	# native host, then runs both.
	#
	# make # fetch + build + run everything
	# make ZIG=/path/to/zig
	# make OPT=ReleaseFast
	# make VERSION=v4.5.0 # test a different release (run `make distclean` first)
