[New-bugs-announce] [issue42827] Multiline eval with assignment to function call segfaults

[Julien Palard]

New submission from Julien Palard <julien+python at palard.fr>:

Tested in 3.9.0 and master (127dde5916):

$ cat test.py
eval(
    """[file for str(file) in []
]
"""
)

$ ./python test.py
python: Parser/pegen.c:149: byte_offset_to_character_offset: Assertion `col_offset >= 0 && (unsigned long)col_offset <= strlen(str)' failed.
Fatal Python error: Aborted

Current thread 0x00007f6454cfe280 (most recent call first):
  File "/home/mdk/clones/python/cpython/test.py", line 1 in <module>
Aborted (core dumped)

(Adding Guido and Pablo to nosy as, IIRC, you're interested in parser things :))
