I've applied the update to 2010c since that apparently fixes some
misbehaviors in obscure time zones (where is America/Godthab???).
However, the proposed addition of explicit clears of the tzstate
struct doesn't match any upstream change that I can see. I inserted
explicit initializations to random data instead and still couldn't
provoke a crash. While it seems harmless enough to explicitly zero
it, I'd like to see an instance of the reported crash, because I have
a feeling that the real problem you're dealing with is elsewhere.
If you can't provoke it reliably, maybe the zeroing didn't really
fix it.
