Range based for-loop crashes with "Chunk size outside of range"

[feliwir]

Hey, i use this library to read .ANI cursor files (https://www.daubnet.com/en/file-format-ani)

However when using a range-based for loop like this:

riffcpp::Chunk chunk(file_buffer, size);

std::vector<char> cursor_data;

for(auto subchunk : chunk)
{
	if (subchunk.type() == fram_id)
	{
		cursor_data.resize(subchunk.size());
		subchunk.read_data(cursor_data.data(), cursor_data.size());
	}
}

The library will just crash inside the for-loop. Are there other ways to iterate chunks?
