Merged requested to merge seitz/walberla:cudaFree-vector into master
How could this have been working until now?
We should not call
cudaFree on uninitialized memory.
We have to free the old pointers before resize. This also prevents memory leakage in case the vector gets shrinked.
Apparently the previous code relied on the fact that
initialized the memory to null pointers or that
cudaFree just ignores
pointers it didn't allocate.
