AMBER: segmentation fault of minimization

Dear Amber Users:

I'm using amber6 to carry out a simple minimization of Plastocyanin in
water following the tutorial at
http://amber.scripps.edu/tutorial/plastocyanin/pcy-tutorial-sh-3.html.

  From the output, it seems MAX_RSTACK should be increased. So I modified
the size.h with the follwing parameters:
-----------
#ifndef MEM_ALLOC
        parameter (MAXREA=20000000)
        parameter (MAXINT=20000000)
        parameter (MAXHOL=1000000)
        parameter (MAXPR=30000000)
#endif
        parameter (MAXDUP=1000)
        integer MAX_RSTACK,MAX_ISTACK,MAX_STACK_PTRS,MAX_HEAP_PTRS
        parameter (MAX_RSTACK=10000000)
        parameter (MAX_ISTACK=10000000)
        parameter (MAX_STACK_PTRS=100)
        parameter (MAX_HEAP_PTRS=100)
-------------
and recompiled it with g77. But I still always get segmentation fault
when I run this minimization. I think the memory should be ok, right?

Attached is the output file and any suggestions will be very appreciated!


Regards!
Liu
