[issue19481] IDLE hangs while printing instance of Unicode subclass

[Terry J. Reedy]

Terry J. Reedy added the comment:

Win 7, console 2.7.5+, 32  bit, compiled Aug 24, does not have the problem. Idle started with 'import idlelib.idle' does, but only for 'print foo', as Tim reported. When I close the hung process with [X], there is no error message in the console. Installed 64bit 2.7.5 fails with 'print foo' also. I actually used F and f instead of Foo and foo, so it is not name specific. A subclass of str works fine.

Current 3.4a4 Idle works fine. The SO OP also reported that there is no problem is the class is imported from another file.

We need a test on something other than Windows, preferably both mac and linux.
