Unable to use Avalon-MM master verification BFM in Questa sim

When vopt is enabled, I have the same issue as reported by someone else in this thread : https://community.intel.com/t5/Intel-Quartus-Prime-Software/Avalon-Verification-IP-example-avlmm-1x1-vhdl-not-working-in/m-p/1516388 .

When using avalon-mm BFM, the first transaction is ok but the second one gets stuck waiting for event_response_complete. The same code was working fine in modelsim.
