[Uml-user] Crash of UML 1.1 beta 1 on Creating a Use Case View

[Andreas Borchert]

Hello,

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.

   #32 0x0006da68 in main ()

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.

Let me finally express my gratitude for developing a free UML tool.
I am glad that there is an alternative to Rational Rose.

Andreas.
