Bug#829716: advancecomp: crashes when using zopfli under armel
Package: advancecomp
Version: 1.20-1
Severity: normal
Hi. (I'm CC'ing the arm list, in case others have seen this problem).
I am using an armel system (some details you can see below) and I'm having
problems recompressing gzipped files with advdef.
In particular, advdef works perfectly when I use the options -z3 (the
enhanced DEFLATE implementation from 7zip) to recompress a file, but it
gives me an assertion error when I use -z4 (which uses zopfli for
compression).
Here is a sample session of a file that has already been recompressed with
-z3, but that shows the assertion error:
,----
| $ advdef -z3 dmesg-1.log.gz
| 4937 4937 100% dmesg-1.log.gz
| 4937 4937 100%
| $ advdef -z4 dmesg-1.log.gz
| advdef: zopfli/lz77.c:104: ZopfliVerifyLenDist: Assertion `data[pos - dist + i] == data[pos + i]' failed.
| Aborted
`----
As far as I could see, this behavior is deterministic with the files that I
have tried so far. I can send the file as a sample if that helps with
debugging.
Thanks,
Rogério Brito.
