Dear Sir,
I tried increasing the MAX_ISTACK value in sizes.h and
the numbers in the error message also changed. but as
i increase the value of MAX_ISTACK beyond 30000000 and
MAXINT beyond 50000000, there is segmentation fault in
the sander. Is there some limit set for these
parameters in amber7. I also want to know that whether
there is a way in which memory can be allocated
dynamically.
Thanks
