[New-bugs-announce] [issue25992] test_gdb fails

[Bryce Miller]

New submission from Bryce Miller:

test_gdb fails for me on OSX

Steps I did to duplicate: 
Checked out fresh '2.7' branch from https://github.com/python/cpython.git
>From the new cypthon dir ran: 
./configure
make
make test
./Lib/test/regrtest.py -v test_gdb

Attached the full verbose output. 

I am looking at Issue23137 and the output messages look different than mine, so I'm posting this as a separate issue. Perhaps it is duplicate. 

34 tracebacks included in attachment, but below is a sample for reference: 

======================================================================
