Thanks for your kind reply.
I just worked out a manual page for mkfs.erofs since I noticed it's a
requirement for a debian package. I think I can upload the whole package to
a github repo or mentors.debian.net website then in a few day.
Could you help take time checking it as well? :-)

I think it's not critical (it only crashes with some given binary
sequences), so I can limit srcsize as a workaround if LZ4 compressor
isn't fixed.
By the way, LZ4HC compressor is not affected at all and it's also
recommended to use LZ4HC rather than LZ4.
However, I'd like to know if some priority to resolve debian LZ4
compressor though. It seems much better than do some workaround on
my side.
Thanks,
Gao Xiang
