Linux で /proc//maps を見たところ、次のようなメモリ領域がいくつかありました。

7ffff74fe000-7ffff7500000 r-xp 00000000 08:01 783399 /lib/libdl-2.11.3.so

7ffff7500000-7ffff7700000 ---p 00002000 08:01 783399 /lib/libdl-2.11.3.so

7ffff7ddf000-7ffff7dfd000 r-xp 00000000 08:01 783381 /lib/ld-2.11.3.so

READ、WRITE、EXECUTE 権限のないメモリ領域 (太字) を知りたいのですが?
