Hey Jaak,
Thank, yeah, but why? :)
My investigation turns up:
shared build works fine and valgrinds clean
static build on g++ (GCC) 4.8.1 (F19) fails
static build on g++ (GCC) 4.4.7 (RHEL 6.4) works fine and valgrinds clean
In the error case, it seems that std::list's c-tor(iterator start,
iterator end) doesn't get called appropriately, though all the other
file globals get initialized just fine.
I moved the global filter in the utility to a stack variable and it
alleviates the problem, but still wonder why the problem in the first place.
Any advice would be appreciated. If I'm doing something wrong, I'd like
to change it, but right now I'm going with "compiler bug" :)

I'm pretty sure that the crash is because the global
const StringList oValues(&choices[0], &choices[2]);
in ../src/modules/filters/utf8greekaccents.cpp:41 is not initialized
when it is used in UTF8GreekAccents::UTF8GreekAccents() to initialize
the global
UTF8GreekAccents greekAccentsFilter;
instance in imp2gbs.cpp:62.
Blessings,
Jaak

I hate to bring this up, now, when we really all want 1.7 out, but
current svn head produces a segmentation fault in imp2gbs. The
other utilities insofar as I tested them seem to be fine.
Below the stacktrace. Tell me if you need more. I basically use
usrinst.sh produced binaries, with the only modification that I
changed the install directory to /usr/local/bin
