commit 0fda2a41baf7e978d07322aa278e964f4dce8802
Author: Florian Weimer <fweimer@redhat.com>
Date: Thu Jul 20 18:31:48 2023 +0200
debug: Mark libSegFault.so as NODELETE
The signal handler installed in the ELF constructor cannot easily
be removed again (because the program may have changed handlers
in the meantime). Mark the object as NODELETE so that the registered
handler function is never unloaded.
