cperl mode hangs when used with narrowing under certain conditions |

Hello,
I just discovered a problem that makes my emacs (21.2 on HPUX 10.20) hang.
[First of all:
Congratulations (I _really_ mean this !)
This is the first problem in emacs for many year which breaks it]
System:
emacs 21.2 on HPUX 10.20
Compiled with HP tools and Motif
Perl/Micro-docs/Cperl-version gives: The version of master-file for this
CPerl is 4.32
Reproduce:
Start emacs with '-q' and probably --no-site-file (see below)
Load this into a buffer:
-------------------- snip, snip -----------------------
{
# 'next LINE;'
# 'next PAT;
}
-------------------- snip, snip -----------------------
Switch cperl-mode on
Narrow the buffer down to the region starting with the first comment-line
and ending with the last.
(It now should look like this:
# 'next LINE;'
# 'next PAT;
)
Position the cursor on the beginning of the first comment-line
Press <TAB>
=> emacs freezes; it has to be killed
This happens for me with both cperl 4.32 and 4.23 (coming with emacs)
I have to use the site-start-file to get the newer one:
This just contains:
(setq load-path
(append (list "/pd/site-lisp/"
"/pd/site-lisp/pcl-cvs")
load-path))
(msb-mode)
TIA - and thanks for a great tool for a great language !
Martin
PS:
I thought, that cperl got confused because of the keywords in the comment.
But this
-------------------- snip, snip -----------------------
{
# fdgshj dsghsdj öjmäcxm
# dsfj gdsjdgs ljdsfhl
}
-------------------- snip, snip -----------------------
gives the same behaviour ! (Only tested with 4.32)
- cperl mode hangs when used with narrowing under certain conditions,
