Well the linux VM build process is so complicated, fraught with issues, and requires such careful tool usage I currently have clients who pay for the results like above so it's not fair to them to disclose the information. I can say I think the VM you are building doesn't appear to be using the gunified version of interp.c you should carefully log and check the output from the build to confirm what source being compiled and how it's be compiled is what you think is going on. Lastly what version of GCC are you using? There can be clue there that I've talked about in the past. As mentioned in the earlier note perhaps the easiest path is to invest in the Intel compiler for Linux. -- =========================================================================== John M.
