This looks like you are linking libgcc statically, but load libpoppler
dynamically? If so, couldn't it be that global data structures from the
static library and the dependencies on libgcc in libpoppler collide for
example if the versions do not match? Have you tried to replace with
libpoppler with any other dynamic link library from the devlibs
collection that references printf? Have you tried not to link statically
with libgcc?

Best regards, Adam.
