Bug in ebrowse

[Markus Gritsch]

Hi,

the C++ header file which led to the problematic BROWSE file reads

namespace test {
     class Base
     {
     };

     class B : public Base
     {
     };
}

class A : public test::Base
{
};

The *Tree* is then displayed as

   *Globals*
   test
   test::Base
     test::B

The class A seems to be missing.


Thanks for reading,
Markus

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 emacs-pretest-bug@gnu.org mailing list.

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

The problem happens when using ebrowse.  Here are the steps.

1) create the BROWSE file
2) visit this file. ebrowse will be "reading data" and all is fine.
3) in the "c++ tree" buffer, move the cursor to a class and do "L-v".
4) the "members" buffer shows up with class info - good.
5) goto "c++ buffer" again and repeat 3)
6) error occurs: (wrong-type-argument number-or-marker-p nil);
traceback is as follows.

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
/usr/local/share/emacs/22.0.50/etc/DEBUG for instructions.

I checked out of ebrowse.el with rev 1.38 and rebuild emacs. The problem is
still there. Do I need to check out other files too?

In addition to the scenario I described before, I noticed that if I delete
the member buffer everytime before I do "L-v", everything works fine.

Probably you didn't byte-compile ebrowse.el.

Re: Bug in ebrowse

[Ping]

I rebuilt the whole emacs...although I didn't check everything out from CVS,
only ebrowse.el...

Do a `cvs up' and `make bootstrap'.  If the problem persists, please
send a clear self-contained recipe for whatever the bug you see.

Re: Bug in ebrowse

[Ping]

it works now. thanks.
