I'm excited to see work continuing (resuming?) on the AST tree. I don't know how many machines you've been able to test the AST branch on. I have a linux/amd64 machine handy and I've tried to run the test suite with a fresh copy of the ast-branch.
test_trace segfaults consistently, even when run alone. You didn't give me the
impression that the failure was a segfault, so I'll include more information
about it below.
With '-x test_trace -x test_codecencodings_kr', I get through the testsuite run.
Compared to a build of HEAD, also from today, I get additional failures in
test_genexps test_grp test_pwd test_symtable
and additional unexpected skips of:
test_email test_email_codecs
The 'pwd' and 'grp' failures look like they're due to a change not merged from
HEAD.
I'm not sure what to make of the 'genexps' failure. Is it just a harmless
output difference? I didn't see you mention that in your message.
Here is some of the relevant-looking output:
$ ./python -E -tt ./Lib/test/regrtest.py
