DSim crashed on array access

Hi,

I was playing with DSim on the Linux system (DSim version 20240422.6.0)

and I found weird crash:

dsim: sv/SVBitSpan.cpp:99: bool dsim::sv::GetSIAndSpanFromExpr(dsim::sv::SVStoreItemRef&, dsim::sv::SVBitSpan&, dsim::sv::SVExprRef, bool): Assertion `0 && "can't refine span"' failed.

I've created small example that triggers this error.
