There's not nearly enough info here to diagnose the problem, but
if I had to bet I'd bet on a memory-management bug that just
accidentally fails to fail in the freshly-reconnected case.

The first thing you should do, if you didn't already, is to build
the backend with --enable-cassert to turn on assorted memory allocation
checks. That might make the bug happen consistently, which would be
a good thing. After that, I'd try capturing a stack trace from the
point of the error report, in hopes of narrowing down what code is
causing the problem.
