The fuzzer detected a serious parsing error; a struct containing a vardecl with multiple declarations would interpret arrays incorrectly. An array would be applied to ALL variables in the decl after its initial appearance. That is, `int w, x[10], y, z;` would be interpreted as `int w, x[10], y[10], z[10];`. The fuzzer caught this by putting two arrayed variables in a row; the second variable was interpreted as a nested array, which led to an assertion. This CL contains a simple hand-written test case demonstrating the bug, with the fix coming in a followup.
