Initial Comment:
cqp v3.4.4 with PrintMode sgml and PrintOptions hdr enabled crashes with core dump. Platform: Ubuntu 12.04 64 bits.
Here are the steps to reproduce it:
cqp -r <registry>
set PrintMode sgml;
set PrintOptions hdr;
[];

Message:
I have tracked it down now and fixed it in SVN (commit 326, version bumped
to 3.4.5). 

Turned out the problem was <time.h> not being included (<sys/time.h> was
included, which *ought* to itself include <time.h>, but for whatever reason
this was not working out). This caused a segfault when ctime() was called
in the construction of the concordance header. I've added <time.h> to the
other output modes (ascii, latex, html) as the same bug would seem to be
present there.

Message:
Did you select a corpus? I can't reproduce this on Ubuntu 11.04, when I set
those options and run a query without having selected a corpus, all I get
is the "No Corpus activated" error message.
