New submission from Serhiy Storchaka:
It is possible to crash Python by breaking opened gdbm database.
>>> import _gdbm as dbm
>>> db = dbm.open('x.db', 'n')
>>> open('x.db', 'wb').close()
>>> db[b'a'] = b'b'
gdbm fatal: read error
Proposed patch tries to convert fatal gdbm into regular exception or in Python
fatal error (which at least produces traceback).
>>> import _gdbm as dbm
>>> db = dbm.open('x.db', 'n')
>>> open('x.db', 'wb').close()
>>> db[b'a'] = b'b'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
_gdbm.error: gdbm fatal: read error
