libstdc++/4548

[Paolo Carlini]

Since a self-contained testcase did not show up, I went ahead and
reconstructed one myself submitter's hints, which indeed demostrates a
serious (albeit rare) problem of the current basic_string::reserve.

Patch posted as http://gcc.gnu.org/ml/libstdc++/2001-11/msg00150.html

Cheers,
Paolo Carlini.
