Test case and plist output
The repeated execution of the following analysis on the attached test case:
clang++ --analyze -Xclang -analyzer-checker=alpha.unix.Stream
test__alpha_unix_Stream.cc
shows two different results: none or one bug warning report; look at the two
attached ".plist" file.
Trunk revision: 176090.
Build version: Debug+Asserts.
E.g. repeating 1000 times the analysis, on one test node I get 62% warning
output(Arch Linux, not virtualized, llvm/clang builded with: clang 3.2), on an
other 24% (Ubuntu 10.04, virtual machine, gcc 4.4.3).</pre>
