I found this with the Template Framework JDK-8344942.

java --add-modules=jdk.incubator.vector -Xbatch -XX:UseAVX=3 Test.java

Does not seem to reproduce with AVX2.

Product: SIGFPE (probably the modulo on line 447 below).
Debug: assert

This is the relevant code snippet:

    440 default:
    441 assert(0, "no valid evex tuple_table entry");
    442 break;
    443 }
    444
    445 if (vector_len >= AVX_128bit && vector_len <= AVX_512bit) {
    446 int disp_factor = tuple_table[cur_tuple_type + mod_idx][vector_len];
    447 if ((disp % disp_factor) == 0) {
