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.
