Re: [Sqlrelay-discussion] Glibc error with Java API

[Ionut C. <ion...@av...>]

No, it was me. It was happenning with an oracle back-end and php API, when
fetching clobs containing unicode characters.

I attached the old e-mail I sent initially. Last time I tested on 0.37
stable it was still happenning.

Note that in that old e-mail I said it wasn't happenning in 0.34. What we
later discovered however was that there was no segfault (and no obvious
memory leak), but the unicode chars and large fragments of text around them
got silently truncated.

Regards,
Ionut
