FW: Patch for zic(8)

[Olson, Arthur David (NIH/NCI)]

Mike Heffner is not on the time zone mailing list; direct replies
appropriately.
Mike's fix is to a modified version of zic.c,
so it doesn't apply to the version archived at elsie.nci.nih.gov;
I'm sending it along for those of you who are using the modified version.

Subject: Patch for zic(8)


Hi,

The attached patch prevents 'zic -m foobar' from segfaulting and also
fixes a memory leak. Can this be applied to FreeBSD's zic codebase or the
vendor codebase?


Thanks,

Mike
