copy of unintialised field fails at run time

[dschwoerer]

Field3D a;
Field3D b=a; // segfault

Expected result:
a) throw BoutException
b) ignore (don't copy, as there is nothing to copy)

I'm not sure what would be the better solution.

I can't reproduce this. Running the code:

#include <bout.hxx>
int main(int argc, char** argv) {
BoutInitialise(argc, argv);

Field3D a;
Field3D b = a;

BoutFinalise();
return 0;
}

I get

terminate called after throwing an instance of 'BoutException'
====== Back trace ======
-> Field3D: Assignment from Field3D
what(): Field3D: Operation on empty data

Is CHECK disabled in your test?

[dschwoerer]

Your right, CHECK was disabled.
Sorry for the inconvinince.
