Good tip, I've never used valgrind before, ran it for about a minute:

==15136== 32768 bytes in 1 blocks are possibly lost in loss record 474
of 483
==15136==    at 0x1B902D7A: calloc (in
/usr/lib/valgrind/vgpreload_memcheck.so)
==15136==    by 0x1C93F1C6: (within /usr/qt/3/lib/libqt-mt.so.3.3.4)
==15136==    by 0x1CC65C24: mngzlib_alloc (in /usr/lib/libmng.so.1.0.0)
==15136==
==15136==
==15136== 603742 (144990 direct, 458752 indirect) bytes in 60 blocks are
definitely lost in loss record 482 of 483
==15136==    at 0x1B902D7A: calloc (in
/usr/lib/valgrind/vgpreload_memcheck.so)
==15136==    by 0x1C93F1C6: (within /usr/qt/3/lib/libqt-mt.so.3.3.4)
==15136==    by 0x1CC5CABD: mng_init_rowproc (in /usr/lib/libmng.so.1.0.0)
==15136==    by 0x1CC2C20F: (within /usr/lib/libmng.so.1.0.0)

So it has something to do with libmng, the c++ version doesn't lose
anything to while and valgrind shows there is no loss to libmng.
