Jon Trulson 606df517f0 dtprintinfo: Fix SIGSEGV in dtprintinfo (passing NULL as first argument to catgets). ... Patch from Douglas Mencken <dougmencken@gmail.com>: The issue is that MESSAGE tries to invoke catgets with NULL first parameter, which is dereferenced inside catgets (Std C Library function) without checking, from catgets.c source: if (catalog->name_ptr[idx + 0] == (u_int32_t) set && catalog->name_ptr[idx + 1] == (u_int32_t) message) On the other hand, there's a special value: -1 (cast to nl_catd), which must be used instead of 0 (NULL) in the case when we are unable to provide real catalog_desc, from catgets.c source: /* Be generous if catalog which failed to be open is used. */ if (catalog_desc == (nl_catd) -1 || ++set <= 0 || message < 0) return (char *) string;		2012-08-06 17:12:38 -06:00
