I found this with the Template Framework JDK-8344942.

At the end of unsigned_mod_value, we compute:
return TypeClass::make(static_cast<Signed>(dividend % divisor));

But in this example, the "divisor" is zero, which leads to SIGFPE.

The SIGFPE happens both in debug and in product.

java -Xbatch -XX:CompileCommand=compileonly,Test::test* -XX:CompileCommand=printcompilation,Test::test* Test.java
