[New-bugs-announce] [issue34310] Build error with option "--with-pydebug" on Mac OS 10.13.6

New submission from Wu Yu <chaconnewu at gmail.com>:

I'm encountering a build error from the master branch of CPython (heads/master-dirty:d17fe275a3) on Mac OS 10.13.6, with "--with-pydebug" turned on. 

The error message:

./python.exe -E -S -m sysconfig --generate-posix-vars ;\
	if test $? -ne 0 ; then \
		echo "generate-posix-vars failed" ; \
		rm -f ./pybuilddir.txt ; \
		exit 1 ; \
	fi
Assertion failed: (TYPE(ch) == test || TYPE(ch) == test_nocond || TYPE(ch) == star_expr), function seq_for_testlist, file Python/ast.c, line 1205.
/bin/sh: line 1: 34527 Abort trap: 6           ./python.exe -E -S -m sysconfig --generate-posix-vars
generate-posix-vars failed
make: *** [pybuilddir.txt] Error 1
