           Summary: Crash when creating PSDs
           Product: kst
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kst kde org
        ReportedBy: arwalker sumusltd com


Version:           HEAD (using KDE KDE 3.3.0)
Installed from:    Compiled From Sources
OS:                Linux

PROBLEM:
Kst crashes when requesting a PSD

STEPS TO REPRODUCE:
Start Kst
Start the data wizard
Select a large data source with many columns
Select the "XY and power spectrum" option
Select the FFT length to be 2^24
Click Finish on the wizard

RESULTS:
Crash (this depends on the amount of free memory you have).
If you have too much run a memory stress testing application
before running Kst.

EXPECTED RESULTS:
No crash. No PSD is created, but a warning message is added to the debug log.

STACK TRACE:
Using host libthread_db library "/lib/tls/libthread_db.so.1".
