Description Havoc Pennington 2002-02-28 20:09:23 UTC 
Not sure if this is a bug or intended behavior:

$ mkdir /tmp/testing
$ cd /tmp/testing
$ touch libc.so
$ touch libc.so.6
$ LD_LIBRARY_PATH=. ls
ls: error while loading shared libraries: ./libc.so.6: file too short
$ LD_LIBRARY_PATH=/usr/lib ls
libc.so  libc.so.6
$ LD_LIBRARY_PATH=/usr/lib: ls
ls: error while loading shared libraries: libc.so.6: file too short
$ 

People do "LD_LIBRARY_PATH=/foo:$LD_LIBRARY_PATH" in scripts pretty often.

According to Ulrich, this is mandated by ELF gABI:
