debug stub, stress testの追加．
及び，pointer access化でenbugしたviolationをmudflapでdebug'n'fix．
[Added debug stubs and steress test rules.
And then, for debug'n'fix enbugging due to pointer accessing,
added violation detection rules w/ mudflap.]

Mudflap Pointer Debugging - GCC Wiki

mudflapによるviolationの検出を有効にすると，
意外に動作が遅くなるので，
mudflapを無効にした状態で数をこなして，
SIGSEGVを喰らうパターンを記録して，
固定値でmudflapを有効にしてムニャヘニャするの繰り返し．
gdbで対話的にdebugするのもイイけど，これはこれで具合が良い．
と言うか，CFLAGSとかが凄い事になってるなー． :P
[When use mudflap-enabled binary, it makes its runtime speed
awful^H^H^H^H bit of slow.
So, disabled mudflap and do ton of stress test.
Then, collecting some SIGSEGV pattern, do it w/ mudflap enabled binary.
This way would be awesome for my laziness.
BTW, the CFLAGS or so looks like a bit of rice-flavor! :P]
