Yes: Run LTspice under wine.

Some years back I had a copy of the source for Spice3F?. I spent some
time going through it and finding all of the dereferencing of unassigned
or null pointers. I found about 10 of them and sent the code back to the
person I got it from. The folks that wrote Berk Spice assumed that a
malloc always worked and didn't fully check syntax errors. With crafty
syntax errors, I could send the code through paths where it would
derefence an unassigned pointer. It could be you've found one of these.
Try a netlist with absolutely no errors in it to be sure.
