[New-bugs-announce] [issue32368] Segfault when compiling many conditional expressions

[Stefan Nordhausen]

New submission from Stefan Nordhausen <stefan.nordhausen at solarisbank.de>:

The following code reproducibly segfaults in version 2.7.13, 3.6.3 and the current git master (3.7.0a3+):


code = "42 if True else 43\n" * 200000
compile(code, "foobar", "exec")


This issue was originally found because the Jinja templating engine internally produces large tuples with many conditional expressions, thus triggering this bug (see https://github.com/pallets/jinja/issues/784 ).
