[fpc-devel]Converting between Comp and (U)Int64 types

Hello developers !
if you convert a comp >= 2^31 to an (U)Int64 using round() (required
because they're for any reason not assignment compatible) programs crash
with an FPU exception.
If you use trunc() instead the value is cut to 2^31.
Is there any way to overcome this and make conversions between these types
Here's a short test program:
b : int64;
c := 2200000000; // don't know if this is possible; just generate a
value > 2^31 somehow
b := round(c); // or try trunc() too
Using FPC 1.1 from 20.04.2001. I was told that the same happens with 1.0.4.
