+    ==60741==    at 0x4C26B43: calloc (vg_replace_malloc.c:593)

+
+    For each such error, this class extracts most or all of the first (error
+    kind) line, plus the function name in each of the first few stack entries.
+    With this data it constructs and prints a TEST-UNEXPECTED-FAIL message that
+    TBPL will highlight.
+
+    It buffers these lines from which text is extracted so that the
+    TEST-UNEXPECTED-FAIL message can be printed before the full error.
+
+    Parsing the Valgrind output isn't ideal, and it may break in the future if
+    Valgrind changes the format of the messages, or introduces new error kinds.
+    To protect against this, we also count how many lines containing
+    "<insert_a_suppression_name_here>" are seen. Thanks to the use of
+    --gen-suppressions=yes, exactly one of these lines is present per error. If
+    the count of these lines doesn't match the error count found during
+    parsing, then the parsing has missed one or more errors and we can fail
+    appropriately.
