[New-bugs-announce] [issue38665] Crash when running SQLAlchemy with pyodbc

[Dave Johansen]

New submission from Dave Johansen <davejohansen at gmail.com>:

We're using SQLAlchemy 1.3.10 with pyodbc 4.0.27 in the python:3.7.5-alpine docker image to connect to a MySQL 13.0.5026.0 database and it's crashing with the following error:
python: malloc.c:2406: sysmalloc: Assertion `(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed.
