Package: lrzip Version: 0.631-1 Severity: normal Dear Maintainer,
Sometimes, lrzip can't decode its own output. Oddly, this *only* happens when the compressor stage is run as a pipe. I've minimized this testcase from a larger one, in which I used the entire script I was using to test various compressors as the input. $ printf 'zp c1 output.1.zpaq input\nzp c2 output.2.zpaq input\nzp c3 output.3.zpaq input\n' | lrzip | lrunzip | cat Decompressing...
