GC ??

[dv . praveen]

hi,
I am using guile 1.6.0. and programming in C.

I am using scm_boot_guile and scm_shell in the function
I pass to scm_boot_guile.  All the SCM objects that are
created, say using 'scm_make_string', 'scm_make_vector'
etc, and assigned to globals don't seem to exist after
call to scm_shell is made.  My code looks something like
this..

#include <libguile.h>
static SCM vector;
static SCM
retVec()
{
    return vector;
}
static void
CreateVector()
{
    vector = scm_make_vector(SCM_MAKINUM(2), SCM_EOL);
}
static void innerMain(void *closure,
        int argc,
        char **argv)
{
    CreateVector();
    scm_c_define_gsubr("retVec", 0, 0, 0, retVec);
    scm_shell(argc, argv);
}
main(int argc, char **argv)
{
    scm_boot_guile(argc,argv,innerMain,0);
}

After I built the program, and call (retVec) on the
'guile>' promt, it doesn't return vector
'#(() ())'  Then I tried to create guardian and protect
'vector' but it doesn't work.  As far as I understood
GC, it should not free any global variables.  Am I missing
something in my understanding?  Any suggestion on how to
make this work would be helpful.
BTW, after I create guardian I used gh_call1 to call the
guardian procedure.(depreciated, but I could not figure out
how to call using SCM interface)

Praveen
