Description of problem: Run help from ngspice. The Help window opens. Now close the help window. Program crashes. Version-Release number of selected component (if applicable): ngspice compiled from ng-spice-rework revision 17 How reproducible: Always 100%
Why did you compiled ngspice-rework-17 ? Do a yum install ngspice The current ngspice release on the mirrors is 18-1.fc10 However if the X clone button is clicked on, I encountered the same error. But there is also a "quit help" button.
Sorry. By mistake I entered the wrong version. The version is 18.1-fc10 and yes the error is reproduced if the X button is clicked.
I can confirm this bug. The program doesn't actually crash, but instead exits abruptly with a status code of "1". The only thing I did in the help window was close it by clicking on the "X" of the WM. Below is the output reported by gdb. There is no backtrace because ngspice actually exits (with a status code of "1"). Marking as ASSIGNED as this is easily reproducable. $ gdb ngspice GNU gdb Fedora (6.8-29.fc10) Copyright (C) 2008 Free Software Foundation, Inc.

Can you test and confirm the fix please ? http://chitlesh.fedorapeople.org/RPMS/ngspice-18-2.fc10.i386.rpm FYI: The build system is down for maintenance this weekend.
(In reply to comment #4) > Can you test and confirm the fix please ? > > http://chitlesh.fedorapeople.org/RPMS/ngspice-18-2.fc10.i386.rpm This works. With this new rpm the program now performs the expected behavior. --- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Nice, I have an upstream developer claiming some instabilities while characterising his standard cells. I will be investigating it with him and ngspice upstream. This bug is not that critical, so I hope you don't mind I wait one or two weeks. Any bad results from ngspice are alarmingly disturbing (at least for me).
