commit 75f2de448f311807e2493f2a37a980e2d872b229
Author: Mark Wielaard <mark@klomp.org>
Date: Thu Nov 3 13:38:45 2022 +0100
readelf: Check phdr != NULL or shdr != NULL in handle_dynamic.
The compiler doesn't know that when use_dynamic_segment is true,
then phdr should/will be non-NULL and otherwise shdr is non-NULL.
Add explicit checks to help the compiler out and in case an error
is made calling the handle_dynamic function.
