o Minor bugfixes (security):
- Fix a potential double free bug when reading huge bandwidth files. The
issue is not exploitable in the current Tor network because the
vulnerable code is only reached when directory authorities read bandwidth
files, but bandwidth files come from a trusted source (usually the
authorities themselves). Furthermore, the issue is only exploitable in
rare (non-POSIX) 32-bit architectures which are not used by any of the
current authorities. Fixes bug 30040; bugfix on 0.3.5.1-alpha. Bug found
and fixed by Tobias Stoeckmann.
