bug#20440: 24.4; memory corruption

[Neal Becker]

before-change-functions is a variable defined in `C source code'.

Its value is (t syntax-ppss-flush-cache)

Local in buffer test_unframed.py; global value is nil

after-change-functions is a variable defined in `C source code'.

Its value is (jit-lock-after-change jedi:after-change-handler t)

Local in buffer test_unframed.py; global value is nil

I have captured a corrupt buffer.  This time, emacs said 'file has changed, reload?'.  Again it is corrupted.

The 1st diff is that in the corrupted file, the beginning of the file is inserted into the middle of the buffer

Next time it happens, could you save the corrupted buffer to some temp
file, and then compare that with the actual file's content, to get
a more precise description of the corruption?

You say it's a Python file.  What modes/packages do you use to edit
those files?  What does `M-: after-change-functions' and `M-:
before-change-functions' say in those buffers?
