Yes, checked that before... libdrizzle (and conn.cpp) has diverged very
much and there is some danger in that it could break things. I'll check
with upstream for their comment.
If you want, you can just give it a try and compile drizzle with the
patch. As far as I can see, the only required change is to add this line
--- libdrizzle/conn.cc.orig 2014-02-27 19:43:37.811668879 +0100
+++ libdrizzle/conn.cc 2014-02-27 19:44:11.488212682 +0100

}
} while (0);
+ drizzle_state_pop(con);
+
return DRIZZLE_RETURN_OK;
#else
return DRIZZLE_RETURN_COULD_NOT_CONNECT;
(This is in function
drizzle_return_t drizzle_state_connect(drizzle_con_st *con)
The lines-# are for the latest version in sid, but as far as I see it
has not much changed since 7.1.36-stable)
Would be great if you could give it a try and let me know if this fixes
it..
