bug#12568: 24.2.50; semantic parser and python conditional expressions

[Stefan Reichör]

In GNU Emacs 24.2.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.24.10)
 of 2012-09-20 on ubu
Windowing system distributor `The X.Org Foundation', version 11.0.11103000
Configured using:
 `configure '--prefix=/home/srei/prg/stow/emacs''

How to reproduce the bug:
C-x C-f 1.py RET
M-x semantic-mode RET

>>> file content for 1.py
etags_cmd = "c:/emacs/bin/etags.exe" if cRunningOnWindows else "etags"
>>> end file content

This gives the following error:

Idle Parse Error: "#<buffer 1.py> - wisent-python-lexer: endless loop at 13, after (STRING_LITERAL 13 . 13)"

I'm afraid I currently cannot reproduce this, using Emacs from bzr,
revno. 110397.

Loading 1.py and enabling semantic-mode does not give me any
error. Also, calling

  M-x semantic-lex-test

correctly returns

((NAME 1 . 10)
 (ASSIGN 11 . 12)
 (STRING_LITERAL 13 . 37)
 (IF 38 . 40)
 (NAME 41 . 58)
 (ELSE 59 . 63)
 (STRING_LITERAL 64 . 71)
 (NEWLINE 71 . 72))

so the lexer seems to work fine.

I can confirm that it works for me as well with a freshly compiled emacs.

Thanks for your efforts,

Thanks for testing. I guess the problem was fixed with the recent CEDET
update in Emacs. I'm closing this report then.
