Bug#89152: apt: Undefined behaviour while using SPtr<> for new[]

[Raphael Bossek <raphael.bossek@solutions4linux.de>]

Package: apt
Version: 0.5.3
Severity: grave

hi,

while analysing the the latest CVS sources of APT for my project
I found a typo in apt-pkg/policy.cc that can lead to SEGV or at
least memory leaks. Here is a patch that fix it :

    // Apply the defaults..
-   SPtr<bool> Fixed = new bool[Cache->HeaderP->PackageFileCount];
+   SPtrArray<bool> Fixed = new bool[Cache->HeaderP->PackageFileCount];
    memset(Fixed,0,sizeof(*Fixed)*Cache->HeaderP->PackageFileCount);
    signed Cur = 989;
    StatusOverride = false;
