Hi,

example 29 compiles nicely on Windows with the Visual C++ compiler and
MinGW. Unexpectedly the Visual C++ compiled examples works fine, while
the MinGW compiled crashes. A short session with gdb gives:
Program received signal SIGSEGV, Segmentation fault.
0x710d744f in pldtfac (vmin=-315.36000000000001, vmax=31536315.359999999,
factor=0x23fc00, start=0x23fbf8)
at Z:/DevZone/PLdev/plplot/src/pldtik.c:123
123 tm = *gmtime(&t);
(gdb) list
118
119 diff = vmax - vmin;
120
121 if (start != NULL) {
122 t = (time_t) vmin;
123 tm = *gmtime(&t);
124 t2 = mktime(&tm);
125 /* Arg! This is because mktime is in local time and we need to
126 correct for the offset. C time handling really is
broken... */
127 tdiff = difftime(t,t2);
(gdb) print t
$1 = -315
(gdb) print &t
$2 = (time_t *) 0x23fb5c
(gdb) print tm
$3 = {tm_sec = 5, tm_min = 2358452, tm_hour = 64685062, tm_mday = 196608,
tm_mon = 207600, tm_year = 0, tm_wday = 1964002646, tm_yday = 1077411871,
tm_isdst = 16384}
(gdb)
Can't see anything obvious here, maybe a bug in the Standard library of
MinGW. Maybe others can confirm the crash and look into it.

Werner
