I can't reproduce this problem – which does indeed look quite serious – with the latest SVN checkout of CWB and CWB/Perl on our server (also running Ubuntu 16.04), so it will be hard to debug remotely.  Here are a few starting points:

1) Did you make sure to update your Ubuntu installation to the latest versions?  Did you install the package libpcre3-dev rather than an older version?

2) Is it possible that you're picking up a non-standard version of PCRE or Glib2, which might be hanging around in /usr/local? (Not likely unless you installed a version yourself at some point or another admin might have messed around with the machine.)

3) Did you make sure to update the CWB/Perl modules to the lastest SVN checkout?  The log output you showed us

> x86_64-linux-gnu-gcc -c  -I/usr/local/cwb-3.4.12/include -D_REENTRANT -D_GNU_SOURCE -DDEBIAN -fwrapv -fno-strict-aliasing -pipe -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -g   -DVERSION=\"3.00401\" -DXS_VERSION=\"3.00401\" -fPIC "-I/usr/lib/x86_64-linux-gnu/perl/5.22/CORE"   CL.c

suggests that you're trying to install version 3.4.10 of the CWB/Perl module, which might not be compatible with the most recent changes in CWB 3.4.12.  I don't remember for sure, but I think "svn up" would be the first thing to try here.

Hope this helps,
Stefan
