commit 0fda2a41baf7e978d07322aa278e964f4dce8802 Author: Florian Weimer 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.
