Well, this=0x0 should tell you something is not right.

Looks like mysql::transaction::current ().connection () call returns NULL
as current connection. Which is quite strange: if there was no current
transaction, the you should have gotten an exception. And if there is a
transaction, then there should be a connection.

Something strange is going on. Looks like a skew/mis-configured build
or some such. You will have to investigate on your own.
