Description pdenis2 2001-07-04 14:59:51 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.2-2 i686)

Description of problem:
 MATLAB 5.3 (SR_11) startup aborts with (MATLAB) floating point exception
unless user is root.  ***OK under Gnome***

How reproducible:

Steps to Reproduce:
1.From KDE desktop -- Open konsole window (or xterm...)	
2. *As ordinary user* type: matlab

Actual Results:  Matlab starts (opening comments + splash screen) then
aborts with:
      Floating point exception detected at Wed Jul  4 18:42:24 2001

  MATLAB Version: (R11)
  Operating System: Linux 2.4.2-2 #1 Sun Apr 8 20:41:30 EDT 2001 i686
  Window System:    The XFree86 Project, Inc (4003), display :0.0
  Current Visual:   0x21 (class 4, depth 24)
[8 MBcore dumped]

Expected Results:  Matlab

Additional info:

Matlab launches OK if I su root, but I haven't tried using it much that way
(won't).  Since this machine/installation of MATLAB works fine under Gnome
desktop it looks like a KDE problem.  Will also copy The Mathworks.

HW: Athlon 1.2 GHz, Asus K7V, 256 MB RAM/512 Swap
OS:  2.4.2-2 #1 Sun Apr 8 20:41:30 EDT 2001 i686 unknown
 (RH 7.1 with all current upgrades except kernel*rpm)
video=Nvidia GeForce2; same behavior with XFree or NVIDIA drivers
Comment 1 Bernhard Rosenkraenzer 2001-07-05 09:30:23 EDT
Matlab must be doing something odd then - guess they're making some 
assumptions about the root window which don't match what kdesktop/kwin provide.

Since we don't have their source (not even the binaries actually), there is 
little we can do to find a workaround.
