[issue25764] PyObject_Call() is called with an exception set in subprocess

[Martin Panter]

Martin Panter added the comment:

Couldn’t re-enabling garbage collection cause errno to be overwritten? Even if I saved errno until later, there is still the RuntimeError from releasing the import lock to worry about.

Now that I look closer, I see the lock release code path sets this exception, but does not return NULL. Another bug.
