The input can be the diagonal of any NxN matrix alongwith its subdiagonal. If your codes do not have any hidden problems ( processing with smaller arrays works ) then your recursive processing is bound to Physical Memory up to some level and after If you're lucky enough that give you information enough on how to solve the issue. Albert Holguin 10-Apr-11 21:49pm well you pass the address to the array, which is technically the address of the first element of the array, but all you really have https://software.intel.com/en-us/forums/intel-visual-fortran-compiler-for-windows/topic/378429

That dll needed __stdcall convention.  I had changed in my Debug project to __stdcall but forgott in Release. For example, things like this: Code: long double *tmp_DLAMDA; tmp_DLAMDA = new long double [K];//This is where it breaks off for(i=0;i I applied first 3 actions. So the program crashes when it tries to use pos as a pointer.

I'm sure it's a rookie mistake, the fun is to find it. Please take into account that with a 64-bit application maximum amount of memory a 64-bit application can allocate is more than 1TB ( of course a system must have it installed I can't give you exact instructions because I'm on linux at the moment, but I believe if you open the task manager there should be some plots/statistics about cpu/memory usage. weblink When answering a question please: Read the question carefully.

I will try Inspector on Monday, then I will share the results. If I understand what's going on here correctly there must be some (or many) variable/matrix in the program that is being reallocated memory on each loop. It may be several frames up.
