I get on

attaching its vdso.bin.gz
GDB (FSF HEAD 5e43d46791c4c66fd83947a12d4f716b561a9103) regression:
reproducer for Fedora systems (as Fedora glibc is patched):
./gdb -ex r --args $PWD/../../glibc-root/lib/ld-linux-x86-64.so.2
--library-path $PWD/../../glibc-root/lib:/lib64 ./gdb
assuming an untested reproducer for more upstream glibc (Debian?); not tested:
./gdb -ex start ./gdb
actual result / FAIL:
Got object file from memory but can't read symbols: File truncated.
expected result / PASS:
warning: Could not load shared library symbols for linux-vdso.so.1.
Do you need "set solib-search-path" or "set sysroot"?
