References: - Referring: + Referring: foo.constprop.0/8 (addr) ... -foo.constprop.0/8 (foo.constprop) @0x7face3ee75a0 +foo.constprop.0/8 (foo.constprop) @0x7f63734ab2d0 Type: function definition analyzed Visibility: artificial - References: a/0 (write)c/1 (write)a/0 (read)b/3 (read) + References: bar/5 (addr)a/0 (write)c/1 (write)a/0 (read)b/3 (read) which means something is pushing &bar from # DEBUG D#2 => (int) bar which doesn't appear in any non-debug stmts.
