1. Should not evaluate at compile time for this function call/construct
2. The error message is missing proper line # or nothing related to the
module displayed in error message
https://github.com/apz28/dlang/blob/main/source/pham/db/db_fbbuffer.d#L527
I have a feeling that line is backwards.
It says: if the buffer has length, ignore it and use the connection,
otherwise use the (empty) buffer data.
So perhaps this is actually a real error that is being flagged (because
it's inlined)?
In any case, it's possible that fbConnection being null does not mean a
null dereference, but I'd have to see the class itself. I'm surprised if
you don't get a null dereference in non-release mode, unless this code
is never actually called.
