non-zero values after init

on "my machine" sometimes after initialization get_value returns unnatural values, eg;
```
>>>print bmi.get_value("comp outflow olake")
...
5.63086319e+14 4.55548118e-41 5.63086319e+14 4.55548118e-41
6.87891626e+14 4.55548118e-41 6.87891626e+14 4.55548118e-41
0.00000000e+00 0.00000000e+00 0.00000000e+00 0.00000000e+00
0.00000000e+00 0.00000000e+00 0.00000000e+00 0.00000000e+00
0.00000000e+00 0.00000000e+00 0.00000000e+00 0.00000000e+00
...
```
(not always and few values, other vars too)
this seems to indicate an initialization problem somewhere

Start by reproducing the reported initialization behavior and tracing the get_value entry point, using the variable "comp outflow olake" as the example. Check whether initialization consistently assigns valid values, then verify that get_value returns initialized values rather than the reported non-zero garbage across affected variables.
