--- Comment #3 from anlauf at gcc dot gnu.org ---
On my system I don't see glibc complaining, independent of MALLOC_PERTURB_=,
however, with valgrind I do get an invalid read slightly deeper down, in

==21865== Invalid read of size 8
==21865==    at 0x95AD7D: add_dt_to_dt_list (resolve.cc:14470)
==21865==    by 0x95AD7D: add_dt_to_dt_list (resolve.cc:14464)
==21865==    by 0x95AD7D: resolve_fl_derived0(gfc_symbol*) [clone .part.0]
(resolve.cc:15152)

(Note the line numbers may slightly differ from yours.)

So confirmed.
