Hi,
While building your package using our research compiler infrastructure we
noticed that the condition operator resulting from expansion of APPEND_DUR of
src/exportlilypond.c does not typecheck:
The return type of g_string_append is GString*, but append_duration has return
type void. Yet the C standard requires that the second and third argument of
the conditional operator ?: are compatible pointer types (there are several
other cases, see 6.5.15 of the C Standard). Failing this, the compiler may
produce arbitrary code.
The best way to fix this is likely making append_duration return a GString*,
which is easily implemented by a simple return figure;
Best,
Michael ([email protected])
