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

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 ===
