write_matrix_dir crashes #39

Hi,

thanks for the lovely package. I would like to use it for quite a few cells. Everything works nicely until i reach about 5 Million cells. Above this threshold the function write_matrix_dir() and my entire R session cashes. I also do not get a warning or error.
I work in R/4.3.0 and use gcc/10.2.

Do you have an idea what the problem could be? Would increasing the buffer parameter in function could help to circumvent this?

Many thanks and kind regards
