How to repeat:
Build with clang and ASAN. Create a test which includes both binlog_reader and basic_istream and run the test.

Hi,

Can you provide us with a necessary test that includes these two source files ???

We require a repeatable test case for each bug report.

There were some issues in my build script. I was depending on binlog_reader.cc file twice.
