verilator does not currently handle some legal uses of $display. It's not a big deal, but I'm using a library that generates verilog such as:

$write("abc: ", "%h", a);

and

$write("foo: <%d", b, ">");

I've started looking at the code and it looks feasible to group the arguments and generate a VL_WRITEF for each group of arguments that is currently handled by verilator.

e.g.,
VL_WRITE("abc"); VL_WRITE("%x", a);

and

VL_WRITE("foo <%d", b); VL_WRITE(">");
