[New-bugs-announce] [issue21857] assert that functions clearing the current exception are not called with an exception set

[STINNER Victor]

New submission from STINNER Victor:

Attached patch detects (when Python is compiled in debug mode) if functions that may clear the current exception are called with an exception set.

The check avoids loosing an exception.

The problem is that the test_sqlite fails with the patch applied. I will open a new patch for that.

I already added similar checks in functions of Python/ceval.c.
