Phillipp, you can ignore this error. It is a confirmed bug in the Xilinx toolchain, supposedly has something to do with WebTalk. One would have to disable WebTalk which is hard to suppress as it will be active every time when a WebPACK license is being used. It is (?) fixed in the 2018.1 release. https://forums.xilinx.com/t5/Simulation-and-Verification/xsim-gives-stack-dump/td-p/810349/page/5 Peter
