[Clamav-devel] 0.103.3 on 32-bit vs 64-bit systems

[Albert Chin]

We've managed to build 0.103.3 on AIX, HP-UX, Solaris, and RHEL. While
we are able to build using either -m32 or -m64, clamav seems to only
work when built with -m64. Is this to be expected? For example, on
RHEL 6/x86, we get:
  $ freshclam --config-file=/tmp/freshclam.conf --show-progress \
  --verbose
