PR 124260 is about dereferencing a NULL "index" tree when traversing static constructors of global variables. As discussed in the bug, it is unclear whether that is allowed but ObjC compiler creates these at least on 32bit hosts. Ian plans to fix this in the FE in the next stage1 but for this stage4, such entries can be easily skipped in ipa-prop (too). The collected information is used for speculative "devirtualization" ony and so if we miss a relevant entry, it may only result in a "bad" decision whether to do that or not. gcc/ChangeLog: 2026-03-11 Martin Jambor <mjambor@suse.cz> PR objc/124260 * ipa-prop.cc (ipa_analyze_var_static_initializer): Skip a constructor entry if its index is NULL.
