これは以下のパッチで解決します。

そして、SADのmakeにも成功しますが、
mkdir -p /Users/yosimoto/SAD/src/oldsad-amorita-snapshot-563/Documents/example

make: *** [all] Error 2
といったように、何かスクリプトを動かすとcore dumpします。試しに、全く何も書いていないスクリプトをgdb上で走らせてみると

というように、mainを呼ぶ所で死んでいます。ということで、SADが悪いのかgfortranが悪いのかを切り
分けるため、gfortranをtestsuiteにかけてみました。

となるので、まあ、gfortranは比較的まともそうには見えるんですがCC自体が駄目かもしれないので
引き続き調査続行、と行った感じです。
