Subject: Question on re-search-forward and infinite loop
Date: Thu, 26 Nov 2009 22:01:04 +0100 [thread overview]
Message-ID: <874oohxapb.wl%maus.david@gmail.com> (raw)
Hi,
By accident I stumpled on a way to force Emacs in a infinite loop with
`re-search-forward'.
If I create a shiny new buffer, insert something like this:
,----
| (while (re-search-forward "^[ \t]*"))
| Something else
`----
-- go back beyond the while-clause and evaluate it, Emacs enters an
infinite loop. As far as I was able to find out
`re-search-forward' with this regexp moves point to the beginning
of the next line above the "S" of "Something else" and stays there
forever so it never reaches end-of-buffer.
As I dunno much (or better: anything) on Emacs' interiors my question
is: Why does this happen?
Regards,
-- David
