[Bug libc/10253] New: RPATH $ORIGIN breaks if resulting path has colons in it

[trick at icculus dot org]

As the summary says, RPATH with $ORIGIN breaks if the expansion of ORIGIN 
results in a path with colons in it.  More specifically, the path is broken up 
at the colons.

For example, if an executable has RPATH set to $ORIGIN, requires a library 
(libfoo.so) that is in the same directory as the exceutable, and both files 
reside in eg /tmp/a, everything will work fine.  However, if both files reside 
in /tmp/a:b (and not in /tmp/a), the linker will be unable to find libfoo.so.  
If the executable is in /tmp/a:b but libfoo.so exists in /tmp/a, the linker 
will find /tmp/a/libfoo.so in stead of the one in the executable's directory.

I've tested this on Arch Linux 64-bit with glibc 2.10.1, and also on Gentoo 
Linux 32-bit with glibc 2.4.  The results are identical on both systems.

I'll attach a script that illustrates the bug.

Script to reproduce bug

Run the attached script to reproduce.  It'll create a new directory named
rpath-bug, enter it, and compile a small library named libfoo.so and an
executable with RPATH set to '$ORIGIN'.  Then it'll copy the files around to a
couple subdirectories with or without colons, showing results of ldd etc.

Here's the output I get when running the script in /tmp:

=== /tmp/rpath-bug ===

Any chance of getting this fixed?  I just triggered it in a production system
(oops!)
