Segmentation fault error when running _PGMCALL to call ILE program from C code running in PASE

gistfile1.txt

// steve8c.c - use _PGMCALL to call ILE program, no parameters.

// to compile:
// gcc -o steve8c steve8c.c   

#include <stdio.h>     
#include <as400_protos.h>

  int main(int argc, char *argv[])    
  {    
    int rc;
    static ILEpointer ilep_sample1c __attribute__ ((aligned (16)));     
    void *parms_argv[1];

    printf("running ...\n");   

    /* Set the IBM i pointer to the QGPL/SAMPLE1C *PGM object */
    printf("before _RSLOBJ32.\n") ;
   rc = _RSLOBJ2(&ilep_sample1c, RSLOBJ_TS_PGM,
                 "SAMPLE1C", "QGPL" );

    printf("after _RSLOBJ32.\n") ;

    parms_argv[0] = NULL;  
    rc = _PGMCALL( &ilep_sample1c, (void*)&parms_argv, 0);
  }
  

when I run the code I get "Segmentation fault(coredump) " on the _RSLOBJ2 function call. Why that error?

use gcc to compile:
gcc -o steve8c steve8c.c

then I run the code:
steve8c
running ...
before _RSLOBJ32.
Segmentation fault(coredump)

calling a CL program on the IBM i:
PGM
SNDMSG MSG('hello from sample1c') TOUSR(*SYSOPR)
endpgm

sample1c was compiled using CRTBNDCL command:
CRTBNDCL PGM(QGPL/SAMPLE1C) SRCFILE(QGPL/QRPGLESRC)

my gcc version. here is the gcc -v output:
gcc -v
