@martin,
I'm working on this bug, http://bugs.python.org/issue15068
I tried this with gdb
(gdb)run
>>>from sys import stdin
>>>str=sys.stdin.read()
blabla
blabla
blabla
CTRL+D
CTRL+D
>>>CTRL+C
(gdb)backtrace
0xb7f08348 in ___newselect_nocancel () at ../sysdeps/unix/syscall-template.S:82
82 ../sysdeps/unix/syscall-template.S: No such file or directory.
in ../sysdeps/unix/syscall-template.S
Current language: auto
The current source language is "auto; currently asm".

But i can't get any clue which file to look at.
