The parser crashes when there are some syntax errors from stdin:

> echo "(1+34"  | ./python.exe -
[1]    54046 done                echo "(1+34" |
       54047 segmentation fault  ./python.exe -

I think we should look into having some variable holding all the text that we have parsed so far. All the workarounds to fetch the text from the file or from stdin or whatnot are getting very very complicated.

I modified PR 24763 to implement this idea.
