Is it a bug?

I guess it can be seen as a bug, or just as a limitation of that 
apparently LDC-specific feature. IIRC, it just checks for calls 
to functions in a hardcoded list of GC-allocating functions (may 
not be up-to-date, as it's probably not widely used) and 
apparently doesn't differentiate between runtime and compile-time 
interpretation.
