[Bug libmudflap/19319] Mudflap produce many violations on simple, correct c++ program

The reduced testcases listed previously in this thread indeed work correctly on
the mainline, but a real C++ program that I tested still spewed thousands of
violations, although valgrind could not find anything. The attached test case
test.cc is one such example. Note that the test program tries to read its own
source, so don't rename the file!
