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

[David M. <dav...@fi...>]

I think I remember someone reporting this before, maybe you :)

Those errors generally occur when there's a double free or an
uninitialized variable.  I'll look through the code for something like
that, but if you can narrow down which queries cause the crash, it'll be
a lot easier to figure out.
