Simpler example of failing C source code

This is a simpler example of failing C code (which won't
make peoples' eyes cross from looking at converted Fortran
DO loops and array indices), and which also has its variables
initialized.

The error is the same:
$ gcc -O1 sl4-error.c
$ ./a.out
Segmentation fault
$ gcc -v ; gcc -dumpmachine
Using built-in specs.
Configured with: ../gcc-4.0-20050123/configure --prefix=/home/zfkts
--enable-languages=c,f95
Thread model: posix
gcc version 4.0.0 20050123 (experimental)
ia64-unknown-linux-gnu
