I seem to have encountered a false positive with valgrind-3.13.0 with
the program below.

Valgrind gives "invalid read" errors show the following pastebin:
https://pastebin.com/a4vzNMvW.
The error is reported during the second call to w_strdup_printf on
address of string a (which is created during the first call).
If I uncomment the printf calls, the errors disappear. If I move free(a)
next to free(b), the errors also disappear.
I am not sure if I am missing something in my program or if those are
real false positives.
You have used ap twice, the second time after va_end.
I think you meant to pass ap_copy to the vsnprintf calls (and to
the va_end calls).
