Fixed a crash on garbage code. The test input was found by afl_cppcheck (type2). Unforunately, the cppcheck-fuzzer-client was crashing only when executing the binary input from afl-fuzz. Using the translated-input (C-code) did not lead to crash. I tested it with activated address/undefined behaviour sanitizer as well as non-instrumented source code. Since the translated output is too long (164 lines), i will not add it the testgarbage.cpp.
