I think again this is a too small stack problem.  It sounds like 
T is about 8 bytes * 60,000 or 240K big and on the stack.  Using
"others" forces it to be initialized to 0.0.  If you don't say
others the memory is uninitialized.  So adding others trips
the fact your stack is too small and gives writes to the wrong

report at or chat at but I think the problem is 
insufficient stack space.
