Question about gmp-chudnovsky.c

My segfault woes were solved when I configured GMP with --enable- 
alloca=no, or --enable-alloca=malloc-reentrant forcing the variables  
to malloced instead of coming off the stack.  You might-could  
allocate more stack memory for your program, but I'm not entirely  
sure how to do that in Debian-a google search would probably turn up  
some techniques.
