Hi Pavel, Please provide a short complete code example (that compiles) that reproduces the problem. If I understand what you are attempting, it appears that you'll need to set your system to support 128 GB of stack. The default on many systems is in the 4 MB to 16 MB range (my system is 8 MB), although I've worked on some that only supported 256 bytes of stack. Note: the stack size on many platforms is not determined by the compiler, it's determined by the OS. Make sure that you have sufficent memory installed on your system. HTH, --Eljay
