Hi,
on MinGW/Win32 (3.4.5 and 4.3.2) example 29 crashes:
Program received signal SIGSEGV, Segmentation fault.
0x10018c7c in pldtfac (vmin=-315.36000000000001,
vmax=31536315.359999999, factor=0x23fbb0, start=0x23fba8)
at Z:\DevZone\PLdev\plplot\src\pldtik.c:123
123 tm = *gmtime(&t);
(gdb) print t
$1 = -315
(gdb) print gmtime(&t)
$2 = 0
(gdb)
gmtime() is called with a negative value, 0 is returned, and if that is
dereferenced than it crashes. I found two postings in the internet:
http://markmail.org/message/55gg5qz6c26a4edd
http://www.nntp.perl.org/group/perl.perl5.porters/2008/07/msg138464.html
which basically say, that gmtime in MinGW doesn't except negative values
and Visual C++ allows them only from the 2008 version on (which I happen
to have installed, that's why it worked for me with Visual C++).
I know that this time stuff is not finished yet, but still we should do
something about that, e.g. checking the return value of gmtime not to be
zero.
Any comments?
Werner
