cpython/Lib/test/crashers
Brett Cannon 1e534b5425 Fix a crasher where Python code managed to infinitely recurse in C code without
ever going back out to Python code in PyObject_Call().  Required introducing a
static RuntimeError instance so that normalizing an exception there is no
reliance on a recursive call that would put the exception system over the
recursion check itself.

README

This directory only contains tests for outstanding bugs that cause
the interpreter to segfault.  Ideally this directory should always
be empty.  Sometimes it may not be easy to fix the underlying cause.

Each test should fail when run from the command line:

	./python Lib/test/crashers/weakref_in_del.py

Each test should have a link to the bug report:

	# http://python.org/sf/BUG#

Put as much info into a docstring or comments to help determine
the cause of the failure.  Particularly note if the cause is
system or environment dependent and what the variables are.

Once the crash is fixed, the test case should be moved into an appropriate
test (even if it was originally from the test suite).  This ensures the
regression doesn't happen again.  And if it does, it should be easier
to track down.
