I ran valgrind on eeschema and found a couple of trivially fixable bugs: 1) EDA_DRAW_FRAME::m_showOriginAxis is never initialized in the constructor 2) LIB_RECTANGLE and related classes sscanf data read from a file using "%s" without field limits, which can cause problems with malformed/really long inputs. 3) If some of the optional fields in a lib line are missing, "tmp" can remain uninitialized.
