Summary | 0001385: Crash when day animation is activated in a far past epoch | ||||
Description | If a day forward animation is activated in a far past enough epoch, the program crashes with a floating point error. As a consequence, skychart.ini file is written with something wrong, and the program does not work properly anymore. SW ver. 3.11-svn-3065 | ||||
Steps To Reproduce | 1 - Start the program 2 - Set the epoch 2500 b.C., 25 June, 05:30:00 (CET) 3 - Select animation by day 4 - Start animation 5 - Click on "Cancel", the program aborts 6 - Start the program, it does not work properly (see attached image). In order to restore the normal functionality of the program: 7 - The already running "invisible" instance of skychart.exe must be killed 8 - The following files must be replaced with a backup copy: - cdc_trace.txt - cdc.db. | ||||
Additional Information | At step (5), if you click on "Ok" the program does not abort, anyway it does not work properly, it is impossible to exit by means the normal procedure and the process skychart.exe must be killed. | ||||

Important: stuck or crash occurs if asteroids or comets are activated. |
|
The problem is because the program try to use a recent comet element for this epoch. And an element for an hyperbolic orbit give very weird result after 4500 years. This is fixed by revision 3068: http://sourceforge.net/p/skychart/code/3068/ |
