[New-bugs-announce] [issue18605] 2.7: test_threading hangs on Solaris 9

[Maciej Bliziński]

New submission from Maciej Bliziński:

Python version: 2.7.5
OS: Solaris 9
Architecture: sparc

Looks similar to Issue5114 and Issue6643 but both are now closed.

It seems specific to Solaris 9, I'm not seeing this issue on Solaris 10.

The symptom is that test_threading hangs indefinitely (tested overnight) . When running pstack on the process, I'm seeing this:
