[uWSGI] Crash on touch-chain-reload

Hello.

I'm seeing uwsgi workers crash when they are chain-reloading. This appears to be when they are about to die anyway, so it's not a problem, but it's probably something easy to fix. It's not easily reproduced, it seems to happen only when the worker has been up for some time. If I try to chain-reload shortly after these crashes, all workers reload fine. After "some time", when I try to chain-reload ALL workers crash with this stack trace:

*** glibc detected *** webclient uWSGI worker 8: free(): invalid next size (normal): 0x0000000001a1b4a0 ***

This is the config of this uWSGI instance:

The uwsgi version is 1.9.15. This instance does not use gevent or defines custom atexit()s.

Any clues on what the problem may be? This is the only instance where I'm seeing crashes on touch-reload, btw.

Thanks,
André
