Describe the bug

After using patchelf --set-rpath on a library from a recent Firefox Nightly build, the library can no longer be loaded because it segfaults the linker.

Steps To Reproduce

• Download and unpack https://download-installer.cdn.mozilla.net/pub/firefox/nightly/latest-mozilla-central/firefox-119.0a1.en-US.linux-x86_64.tar.bz2
• Attempt to dlopen any of the .so files (libmozsqlite3.so was my test target), e.g. with python -c 'import ctypes; ctypes.cdll.LoadLibrary("./libmozsqlite3.so")'
• Observe success
• patchelf --set-rpath "test" ./libmozsqlite3.so
• Attempt dlopen again
• Segfault

Expected behavior

No segfault.

patchelf --version output

Attempted both default nixpkgs 0.15.0 and current nixpkgs patchelfUnstable (c401289).

Additional context

This seems to have been caused by upstream enabling some kind of advanced linker wizardry called "relrhack": https://hg.mozilla.org/mozilla-central/rev/032b87ff55061bcbdc7a85d9e18fde814797073a

The last build before that commit works fine.
