Re: core dump from within asctime_r()

ctime() is (of course) just asctime(locatime(t))

locatime() can return NULL these days, and given a nonsense time value (which is quite likely under these circumstances), probably did, but asctime() doesn't expect anything but a valus "struct tm *" and will simply dereference NULL is NULL is returned from localtime() - instant core.

This code follows the C standard, so this bug is a defect in the standard. It has not been corrected in the latest committee draft. http://www.open-std.org/JTC1/SC22/WG14/www/docs/n1425.pdf Tony. -- f.anthony.n.finch <dot@dotat.at> http://dotat.at/ GERMAN BIGHT HUMBER: SOUTHWEST 5 TO 7.
