Huanglei3 reported a bug in lrzip that is not duplicated here

[pete4abw]

heap-buffer-overflow in libzpaq/libzpaq.cpp:1208:25 libzpaq::PostProcessor::write(int)

@huanglei3 , this type of POC work is counterproductive. Yes, lrzip crashes, but lrzip-next does not. See output below (your filenames have been renamed). But, of course, your file is borked, so lrzip-next does crash during decompression. But we use ZPAQ version 7.15.

$ lrzip-next -vvt huanglei3.poc

hi,when i install lrzip-next,i met some errors:
checking libbz3.h presence... no
checking for libbz3.h... no
configure: error: libbz3.h not found. Install libbz3-dev

but no package libbz3-dev.
install bzip3 first?

[pete4abw]

Yes, bzip3 library is a dependency, but my error message is NOT accurate! Thank you I will fix.
Package libbzip3-dev is what you want.
