single patchelf command corrupts symbols

[j4k0xb]

binary/libc: Archive.zip
OS: Manjaro
patchelf: 0.18.0

Gdb can't find any symbols anymore after running pwninit:

$ pwninit --bin rpsls --libc libc.so.6 --no-template
bin: rpsls
libc: libc.so.6
ld: ./ld-2.31.so

copying rpsls to rpsls_patched
running patchelf on rpsls_patched

$ ldd rpsls_patched
        linux-vdso.so.1 (0x00007ffff7fc8000)
        libc.so.6 => ./libc.so.6 (0x00007ffff7dc9000)
        ./ld-2.31.so => /usr/lib64/ld-linux-x86-64.so.2 (0x00007ffff7fca000)

$ gdb rpsls_patched
GNU gdb (GDB) 13.1
...
gef➤  b main
Function "main" not defined.

Same behavior when manually running patchelf with both args:

$ cp rpsls rpsls_patched
$ patchelf --set-interpreter ./ld-2.31.so --set-rpath . rpsls_patched
$ gdb rpsls_patched
GNU gdb (GDB) 13.1
...
gef➤  b main
Function "main" not defined.

Only with 2 separate commands it works as expected:

$ cp rpsls rpsls_patched
$ patchelf --set-interpreter ./ld-2.31.so rpsls_patched
$ patchelf --set-rpath . rpsls_patched

$ ldd rpsls_patched
        linux-vdso.so.1 (0x00007ffff7fc8000)
        libc.so.6 => ./libc.so.6 (0x00007ffff7dc9000)
        ./ld-2.31.so => /usr/lib64/ld-linux-x86-64.so.2 (0x00007ffff7fca000)

$ gdb

I've been hit by this issue as well and opened #299 to fix this.
