From 66b1fe1d4fa67714925ac381c18f8b9cffdb968a Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Thu, 20 Jul 2023 18:31:48 +0200 Subject: 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.
