[vdr] cString operator= with same buffer

Hello list,

I'm wondering what should happen when assigning a cString to another where both have pointers to the same buffer? As of version 1.3.36, we first free it and duplicate it afterwards.

That surely isn't intended, but how to deal with this?

1) Leave them pointing to the same buffer after operator= 2) Don't free the buffer, but duplicate it (that happens in vdr<1.3.36)

Do you see good arguments for 1)? I only have one for 2), as you (I) expect to receive a new copy of cString's buffer you assinged from. And this cString's destructor will take care about freeing memory of the original buffer.

Thanks for your comments, Holger (who feels ashamed to start a discussion about a one-line-patch :-)
