Cannot gm_provide_receive_buffer_with_tag

Hello, 

i seem to be having an odd spot of difficulty with gm-1.1.3:

running this program:

#include <gm.h>
#include <stdio.h>

#define ENVSIZE 256

int
main(){
  struct gm_port *gm_p;
  void *recvBuff;
  
  /* initialize gm */
  gm_init();

  /* get port */
  gm_open(&(gm_p), 0, 0, "foo", GM_API_VERSION_1_1);

  /* allocate an envelope-sized buffer to recv*/
  recvBuff = gm_dma_calloc(gm_p,
			   1,
			   ENVSIZE);
  if (recvBuff != 0)
    printf("dma malloced %p\n",recvBuff);

  /* provide a recv buffer */
  printf("%p posting recv buffers %p\n",
	 gm_p,gm_ntohp(recvBuff));
  gm_provide_receive_buffer_with_tag((void*)gm_p,
				     gm_ntohp(recvBuff),
				     ENVSIZE,
				     GM_LOW_PRIORITY,
				     1);

  gm_finalize();

  return 0;
}

causes a segfault in the gm_provide_receive_buffer_with_tag() call.

gdb gives the following information on an alpha:
0x12000192c in gm_provide_receive_buffer_with_tag (p=0x1201096c0, ptr=0x0, 
    size=1, priority=1, tag=513) at include/gm_internal.h:124
124             *to32++ = *from32++;

Somwhere, it appears that the arguments are getting munged.

Also, when I run it on a Solaris box, I get the same error.

bcheck gives:
signal SEGV (no mapping at the fault address) in gm_copy_to_io_space at
line 124
 in file "gm_internal.h"
  124           *to32++ = *from32++;


I seem to be following the documentation, but I must be going astray
somewhere, any idea where?

many thanks,

arun
