[New-bugs-announce] [issue24227] IndentationError caused by async / await changes in parser

[Arfrever Frehtes Taifersar Arahesis]

New submission from Arfrever Frehtes Taifersar Arahesis:

Revision eeeb666a5365 causes "IndentationError: too many levels of indentation" sometimes, e.g. in regenerated IN.py module (e.g. Lib/plat-linux/IN.py).

$ ./python -c 'import IN'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/tmp/cpython/Lib/plat-linux/IN.py", line 710
    def IN6_IS_ADDR_UNSPECIFIED(a): return \
                                           ^
IndentationError: too many levels of indentation


I attach regenerated version of Lib/plat-linux/IN.py, which allows to reproduce this problem. (Regeneration was performed by Lib/plat-linux/regen.)

I suspect that the problem is in changes in Parser/tokenizer.c.
