Sentry Crash Report:

Description Russ LeBar 2003-03-17 18:06:40 UTC 
Version:            (using KDE KDE 3.1)
Installed from:    Compiled From Sources
Compiler:          gcc 3.2.1 
OS:          Solaris

For example, kmplot will core if the function is f(x)=x^2.  However, f(x)=x*x works. The core dump occurs when OK or Apply are clicked. Running Solaris 8 latest hardware relase on SPARC.

I compiled without debugging code so the backtrace is less than usefu, but here it is (note: KDE does not catch the crash. This is from running gdb kmplot core and then doing a bt).

Comment 1 Russ LeBar 2003-03-17 19:39:35 UTC 
I guess I should add that what I meant by f(x)=x*x works is that some functions 
can be plotted. It is only when a constant is put into the function that kmplot 
will core dump. Even f(x)=2 will cause a core dump!
Comment 2 Waldo Bastian 2004-02-02 14:15:18 UTC 
Can't reproduce, works fine here. (KDE 3.2)
Comment 3 Anne-Marie Mahfouf 2004-02-07 19:18:24 UTC 
Not confirmed, works fine on 3.2 branch and head.
