kst file used during crash
Attached is the kst file that is used when we get the crash. It also crashed
when we generated the same plots from scratch (before we had saved this kst
file for the first time).
It doesn't appear to be connected to interpreting the field as a time. Rather it appears to have something to do with interpreting the LINCOM. The crash occurs even when not interpreting the X axis as a time. The offending field is defined as Time LINCOM 2 cpu_time 1.000000000000e+00 0.000000000000e+00 cpu_usec 1.000000000000e-06 0.000000000000e+00 where cpu_time and cpu_usec are the seconds and microseconds returned by gettimeofday(2).

Can you send me your datafile+kstfile? I really need a testcase for this if you want it fixed in 1.1.1 I can't reproduce it either, and I am looking at the same data, but on a different machine with a different dist. I will get the cryo guys here to try with 1.1.0 now that it is installed. On May 22, 2005 17:22, George Staikos wrote: [bugs.kde.org quoted mail] No testcase, can't reproduce. |
