[Libguestfs] [PATCH v2 0/4] Avoid 0-bytes malloc in bindings

[Pino Toscano]

Hi,

some of the bindings may try to malloc with 0 bytes as size when closing
an handle, because there were no event handlers registered.  Since this
can have different behaviours in POSIX, avoid that situation altogether
by just skipping allocating anything when there were no event handlers.

Thanks,
