Right -- except that false positives from -Wmaybe-uninitialized may actually not be trivial to fix, as demonstrated by the various GCC bugs reported against this option. I was mentioning GDB as an example mainly because of GCC bug 57287, "GCC 4.9.0 fails to build GDB on Ubuntu 12.04", where somebody has obviously stumbled across this. Comment 12 in that bug hints at a false positive that's still present with upstream GCC, AFAIK.
