pypy3.9: Wrong error message/location for generator expression followed by missing indent
This code produces a misleading syntax error in PyPy3.9 (but not in PyPy2, PyPy3.8 and CPython 3.8+):
max(x for x in ) if False: missing_indent

When I originally found this, the missing indent was near the bottom of the file and the genexp was near the top, so it appears that this bug happens regardless of what is in between.
