+If a binary has multiple SHT_NOTE sections and corresponding PT_NOTE
+headers, we can see the error:
+
+patchelf: cannot normalize PT_NOTE segment: non-contiguous SHT_NOTE sections
+
+if the SHT_NOTE sections aren't sized to end on aligned boundaries. An example
+would be a binary with:
+
+  [ 2] .note.ABI-tag     NOTE             00000000000002f4  000002f4

+since the PT_NOTE section at 2f4 covers [2] and [3] but the code
+calclates curr_off should be 314, not the 318 in the binary. This
+is an alignment issue.
+
+To fix this, we need to round curr_off to the next section alignment.
