[Bug c/26542] bogus diagnostic with -pedantic?: format '%p'; expects type 'void*', but argument 2 has type 'A*'

["vz-gcc at zeitlins dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #4 from vz-gcc at zeitlins dot org  2006-07-24 17:02 -------
I'd like to (probably uselessly but still) argue for reopening this bug and
removing this warning. The interpretation of the standard text is open to
questions: IMHO an "A *" pointer is a pointer to void, too, as any pointer in C
is, implicitely, pointer to void. But most importantly I think this warning is
absolutely useless and the only way to get rid of it is ugly (you need an
explicit cast to "void *").

But, again, the most important argument against this warning is that it's 100%
useless. Conversion of any pointer to "void *" is well defined and unambiguous
(even in presence of multiple inheritance) and there is just no situation
whatsoever in which this warning can indicate a real problem. Please consider
suppressing it, thanks in advance!
