This seems unexpected, but you can investigate it a bit more on your end: add
'-v' to gcc command line to see how linker flags differ, run 'readelf -d' on
./test to check how rpath flag changes, or run 'LD_DEBUG=libs ./test' to see
how dynamic lookup decisions are made.
Thanks for the fast answer! See output below (for simplicity not quite
as generified as the output above). What I notice in the LD_DEBUG
output is that in the failing case the run path is used for the first
two library searches (libasan.so.3 and libc.so.6) but not for any
following searches.
