+# Verify that we split C string literals on null-terminators, rather than on
+# symbol boundaries. We expect four dead-stripped symbols: l_str.0, l_str.2,
+# L_str.3, l_str.4, and the auto-generated symbol for the start of the "defghi"
+# string. We also verify that there are only two dead-stripped blocks, since
+# l_str.3 should not have split the block started at "def"... (since this is a
+# C string section we should be splitting on null characters instead of
+# symbols).
