Summary: Program linked with Guile segfaults

Initial Comment:
Hi,

I tried to link the following program with guile:

----8<------------------------------------------
#include <stdio.h>
#include <libguile.h>

static void *
guile_main (void *data)
{
  void *ret = NULL;

  printf ("body\n");
  fflush (stdout);

  return ret;
}

int
main (int argc, char *argv[])
{
  void *guile_ret = NULL;
  int ret = 0;

  printf ("begin\n");
  fflush (stdout);

  guile_ret = scm_with_guile (guile_main, NULL);

  printf ("end\n");
  fflush (stdout);


  return ret;
}
----8<------------------------------------------

and it segfaults. Gdb reports a problem in strsep, in msys-1.0.dll, as usual with this kind of error, I suspect the problem isn't in strsep itself, but in the way it is called (bad args, probably).

I even tried to compile & link libguile/guile.c (from guile-1.8.4.tar.gz upstream package) and it segfaults the same way. Interestingly enough, the binary shipped in guile-1.8.4-MSYS-1.0.11-1-bin.tar.gz does *not* have this problem. To link my C programs, I used `guile-config compile`" -DSCM_IMPORT" to compile (CFLAGS) and `guile-config link` to link (LDFLAGS).
