GNU gv 3.6.7 has been released. It contains the bug fix, so I can close this bug.

Can a release be made to correct this?

It is a problem also on Solaris systems as their libc does not implement strndup.

Fixed in CVS by providing an strndup implementation called GNU_strndup und using it instead of strndup.

Could you please add the following code at the beginning of src/secsscanf.c just after the includes and report me if it helps? If so, I will modify the configure script to conditionally insert this code if needed.

/* begin test code */
size_t strnlen(const char *s, size_t len)
    size_t i;
    for(i=0; i<len && *(s+i); i++);
    return i;

char* strndup (char const *s, size_t n)
  size_t len = strnlen (s, n);
  char *new = malloc (len + 1);

  if (new == NULL)
    return NULL;

  new[len] = '\0';
  return memcpy (new, s, len);
/* end test code */

Thanks for the bug report. Obviously the patch from "2008-09-09  Olaf Kirch <okir@suse.de>" introduces the usage of "strndup". The purpose is to make calls to sscanf overflow free.

I'll check what can be done soon.

Trying to compile gv 3.6.6 on Mac OS X 10.4.11 Intel with Xcode 2.5 I get this:

/usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: Undefined symbols:

3.6.5 did not have this problem.

My understanding based on some brief Google research is that strndup does not exist on Mac OS X.
