As a temporary measure, I have applied the following patch to my copy

This turns
% genhtml --legend --demangle-cpp --output-directory html foo.info
Reading data file foo.info
Found 4 entries.
Demangling 5 function names
genhtml: ERROR: Demangled function name _ZN3subD2Ev maps to different
lines (5 vs 4)

Overall coverage rate:

functions..: 80.0% (4 of 5 functions)
even if the handling of destructors might not be correct, at least it
lets us use genhtml to cover the rest of the functions.
