Sure.  It generates a string such as
"/usr/local/lib/debug//opt/grbx/lib.so",
which is then passed to the libc function 'open', which fails to find the
file.

When I remove the extra slash, open succeeds.

This is glibc 2.5 running under UML in Scratchbox, on Ubuntu.
Gdb is x86-cross-x86, not that that's probably relevant.
