Hi Mark, there seems to be a problem with the timezone patch that we applied recently to our version of dvipdfm: It again segfaults with certain timezone files. I'm not even sure whether /etc/localtime might not be corrupted - but still it should give an error and not segfault. On the other hand, dvipdfm doesn't open localtime, but query it through defined APIs, well.

So the exact patch that we applied is at http://svn.debian.org/wsvn/debian-tex/tetex-bin/trunk/debian/patches/patch-dvipdfm-timezone-crash?op=file&rev=0&sc=0 and Martin's complete bug report is at http://bugs.debian.org/409517 Martin, do you happen to know how tzconfig handles /etc/localtime? On my sarge system, /etc/localtime is a symlink to a particular file below /usr/share/zoneinfo/ (to Europe/Zurich), on my sid system it's an ordinary file. Is there an easy way to find out which of the preprocessor conditional branches we're in? I'm speaking of +#ifdef HAVE_TM_GMTOFF /* Preferred way to get time zone offset */ + tz_offset = bd_time->tm_gmtoff; +#else +#ifdef HAVE_TIMEZONE /* Plan B --- use external variable 'timezone' + /* (may not provide correct offset for daylight savings time) */ + tz_offset = - timezone; +#else /* Last resort --- without more information, set offset to zero */ + tz_offset = 0l; +#endif /* HAVE_TIMEZONE */ +#endif /* HAVE_TM_GMTOFF */ The file is compiled with this command: cc -DHAVE_CONFIG_H -I. -I. -I.. -I./.. -O2 -c pdfdoc.c -o pdfdoc.o TIA, Frank -- Dr. Frank Küster Single Molecule Spectroscopy, Protein Folding @ Inst. f.
