I get the same message as in #105, except I don't get any error messages about opcodes.

TYPE: 31
* Assertion at mini-amd64.c:209, condition 'amd64_is_imm32 (disp)' not met

Stacktrace:

* Assertion: should not be reached at interp-stubs.c:105

Here are the following links to source code on GitHub with the exact lines:
