Using pyfailamlloc, I found various bugs: see issue bpo-18048. Because this issue has been closed, I'm opening a new issue for new bugs.

Since this is tagged "crash", I'm curious if you managed to crash
_decimal. The unhandled return in convert_op_cmp should result in
AtrributeError("object does not have a numerator attribute").

The exception that wasn't set in dec_format should result in a
wrong exception, but not a crash.

vstinner · 2013-11-01T14:47:16Z

I don't have the gdb trace anymore but it was really a crash.

skrah · 2013-11-02T12:34:12Z

Ok, I found it. It was an assert() in debug mode that the MemoryError from
PyObject_IsInstance() was swallowed. In production mode AttributeError
would have been raised.
