Re: [Uml-devel] Mandrake Crash (fwd)   
2002-10-12 21:01  
I've got a report that the Mandrake RPM causes a crash 
when creating a new diagram (through right clicking on 
the left hand list view) then immediatly renameing it by 
pressing a letter key.
I also have a fresh install of Mandrake 9 but am unable 
to find any problems.  I'm at a bit of a loss for debugging 
capabilities.  Has anyone else tried the RPM who could 
report success or failure?

Subject: Re: [Uml-devel] Mandrake Crash
I'm not sure. It doesn't appear to be any specific key.  I 
do a right click and the text box is highlighted. 
The "normal"/expected behavior is that when I hit any 
text key, the highlighted default name will disappear and 
be replaced by the first character I type, i.e. normal text 
select behavior. 
What happens though is that when I hit the any text 
key... crash.

Crash of UML 1.1 beta 1 on Creating a Use Case View   
2002-10-14 11:30  
I have built UML 1.1 beta 1 from sources using g++ 3.2 
(with GNU as and GNU ld) for Solaris 9 (using KDE 
3.0.4). uml crashes due to a SIGSEGV reproducibly:
- Start it with no arguments.
- Select the languages, click away the pop-up window.
- Right-Click ``Use Case View'' in the navigation bar  and 
select ``New'' / ``Use Case Diagram''.
- A name field appears below ``Use Case View''. Move 
the pointer to it, erase the marked text using a 
backspace, and type in the first letter.
Here is the backtrace. I have removed the trace for the 
signal handling.

I tried again with the option ``--nocrashhandler'' to get a 
core file. adb tells me that uml crashed due to an 
access through 0.
Next, I tried to rebuild uml with debugging flags  but was 
unable to trigger this bug using that version.
