[Bug libstdc++/28457] New: ext/pb_ds/regression/tree_data_map_rand.cc fails with a particular random seed.

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

I saw a failure in this test while testing another patch.  I reran the test a
number of times and couldn't reproduce it, but fortunately it prints out its
random seed.  I hacked that value into the initial seed in
util/regression/rand/assoc/rand_regression_test.hpp, and now it fails 100% of
the time:

detected leaks!
0x59c570: 515, 0
