Unison: input_value: integer too large
Experienced on a grml-developer meeting by gebi:
Stupid 32 vs. 64bit problem. See unison’s FAQ and #404697 for more information.
Workaround: just use the 32bit binary on the 64bit system. The real solution would be to use a current version of unison (>=2.27) – though the latest stable release of unison is still version 2.13 from year 2005 :-( – definitely time for a new stable release, no?
