I can provide more information if needed.

[jamadden]

The line mentioned, relstorage/_compat.py", line 127 , is just from relstorage._inthashmap import .... The crash is somewhere down in the import system.

_inthashmap is a Cython module. Its code hasn't changed in 3 years.

Without a native traceback, I can't tell you more than that. All I can say is that the problem is not "here," in that there's nothing I can specifically change that can solve this.

What are the possible differences from the previous version? There are three:

• The compiler/manylinux toolchain used
• The version of Cython used
• The version of boost used

My instinct is that it's something to do with the manylinux toolchain. Did you install the binary wheel from PyPI? If so, I suggest installing from source using your system's compiler.
