Description Roman Fietze 2008-06-07 20:54:21 UTC

Version:            (using KDE 3.5.9)
Installed from:    SuSE RPMs

Take (almost?) any input data, and create a plugin "Interpolation linear". When the dialog opens just klick "Ok" without changing anything to crash kst.

The console shows:

gsl: interp.c:134: ERROR: interpolation error
Default GSL error handler invoked.
KCrash: Application 'kst' crashing...
kst: Fatal IO error: client killed

The backtrace is in the attachment.

Comment 2 Andrew Walker 2008-06-08 19:50:06 UTC

The gsl interpolation routines require a monotonically increasing x input-vector.

Comment 3 Andrew Walker 2008-06-08 19:51:40 UTC

SVN commit 818520 by arwalker:

BUG:163480 Return early if the x-input vector fed to the interpolation plugins is not monotonically increasing.
