+Subject: [PATCH] elf: Move __rtld_malloc_init_stubs call into _dl_start_final
+
+Calling an extern function in a different translation unit before
+self-relocation is brittle.  The compiler may load the address
+at an earlier point in _dl_start, before self-relocation.  In
+_dl_start_final, the call is behind a compiler barrier, so this
+cannot happen.

+Subject: [PATCH] elf: avoid jumping over a needed declaration
+
+The declaration of found_other_class could be jumped
+over via the goto just above it, but the code jumped
+to uses found_other_class.  Move the declaration
+up a bit to ensure it's properly declared and initialized.
