My only question about this patch is why the symbol's section has a non-zero section offset. Is that the reason why? Maybe it would make sense to make a SEC_THREAD_LOCAL section always have a zero offset. Then touching all the users wouldn't be necessary. On the third hand it seems strange to even try to get the "address" of a TLS symbol in this way. Tom
