ログを見るとこんな感じで、getaddrinfoのバグとやらが影響していそうに見える……

……が、上の方を見ると何かがおかしい:

checking size of int... 0
checking size of long... 0
checking alignment of long... 0
checking size of long long... 0
checking size of void *... 0
checking size of short... 0

sizeof int が0????

ビルドディレクトリの config.log によると

sizeof intの値を返すプログラムが死んでいる。9(SIGKILL)なのでsegvではなく外部から殺されている?

心当たりがないわけではない(Trend Micro Security Agent)が、何か検出されたというログは出ていない。

一応試してみる:

# オラオラ
$ while true; do sleep 1; ps ax | grep iCoreService | grep /libTmAntiMalware.dylib | awk '{ print $1}' | xargs sudo kill -9; done
