[issue32758] Stack overflow when parse long expression to AST

[Serhiy Storchaka]

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:

There is also a regression in 3.7 when compile a long expression.

In 3.6:

>>> compile('+a'*1000000, '?', 'eval')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
RecursionError: maximum recursion depth exceeded during compilation

In 3.7:

>>> compile('+a'*1000000, '?', 'eval')
Segmentation fault (core dumped)
