Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs <at> gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


1. `M-! echo 'print ".hello"' > foo.py RET
2. `M-x pdb RET python -m pdb foo.py RET'

I get a *gud* buffer with no prompt.  If I create a little executable
script, “bar”

    #!/bin/sh
    python -m pdb foo.py

and then `M-x pdb RET ./bar RET'

Everything works as expected.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/Applications/Emacs.app/Contents/Resources/etc/DEBUG for instructions.

I'm afraid I can't reproduce this.  I get a *gud-pdb* buffer, as
expected.  Maybe this is operating system specific.

I get a buffer containing

  Current directory is ~/
  > /home/cyd/foo.py(1)<module>()
  -> print "hello"
  (Pdb) 

With "(Pdb)" as the prompt.

Oh, well I don't.  Perhaps it is indeed platform specific.

I just quickly tested this in the emacs-24 branch and worked for me, I'm 
closing this. Feel free to reopen if you find it happening again.
