Bug#869777: yara tests fail on ARM32, when run on a 64bit kernel
Package: src:yara
Version: 3.6.3+dfsg-1
Forwarded: https://github.com/VirusTotal/yara/issues/716
Tags: upstream
yara tests fail on ARM32, when run on a 64bit kernel.
This turns out to be because the codebase is full of code that assumes unaligned
access is OK, for example stuff like this
https://github.com/VirusTotal/yara/blob/master/libyara/exec.c#L224 but also
more subtly stuff like
https://github.com/VirusTotal/yara/blob/master/libyara/scan.c#L409
(new_match is only guaranteed to be 4-byte-aligned and crashes when you access
an 8 byte field).
