I did try that with pointers several different ways. Just tried it again and for the first time this compiled with no errors:

Code:
#include <stdio.h>
#include <stdlib.h>

int main() {

    int c;
    int *test;
    test = &c;

    int a [5] = {1,2,3,4,5};
    int b [5] = {6,7,8,9,10};

    for(c = 'a'; c <= 'b'; ++c) {
        for (int j = 0; j < 5; j++){
            printf("%d\n", test[j]);
        }
    }
}

The output is uniq, but wrong:

Code:
$ ./canloop
97
757351276
32767
0
4
98
757351276
32767
0
4

I guess I'm not dereferencing it right? Maybe I've just been up too long, but I'm open to more suggestions.

DTRACE(1)						      General Commands Manual							 DTRACE(1)

NAME
dtrace - Dtrace compatibile user application static probe generation tool. SYNOPSIS
dtrace -s file [OPTIONS] DESCRIPTION
The dtrace command converts probe descriptions defined in file.d into a probe header file via the -h option or a probe description file via the -G option. OPTIONS
-h generate a systemtap header file. -G generate a systemtap probe definition object file. -o file is the name of the output file. If the -G option is given then the output file will be called file.o; if the -h option is given then the output file will be called file.h. -C run the cpp preprocessor on the input file when the -h option is given. -I file give this include path to cpp when the -C option is given. -k keep temporary files, for example the C language source for the -G option. --types generate probe argument typedef information when the -h option is given. EXAMPLES
Systemtap is source compatible with dtrace user application static probe support. Given a file test.d containing: provider sdt_probes { probe test_0 (int type); probe test_1 (struct astruct node); }; struct astruct {int a; int b;}; Then the command "dtrace -s test.d -G" will create the probe definition file test.o and the command "dtrace -s test.d -h" will create the probe header file test.h Subsequently the application can define probes using #include "test.h" ... struct astruct s; ... SDT_PROBES_TEST_0(value); ... SDT_PROBES_TEST_1(s); The application is linked with "test.o" when it is built. SEE ALSO
