oregano crashes with SIGSEGV when trying to run a simulation

I had also a crash of Oregano on my freshly installed Ubuntu 10.04.

That is; making a circuit goes OK. The simulation starts (gnucap) OK, but when the results are there is the program crashing with a segmentation fault.

Compiling the program from source (the release version 0.69.1) did solve the problem; the program does not crash any more at the end of the simulation. I can see the results of a simulation.

Can it be that the Oregano package of ubuntu is not correctly compiled?
(It uses scons instead of make, because of that is it for me not possible to use checkinstall to generate a decent package myself...)

I'm getting what appears to be the same error. When I ran oregano with gdb and attempted to simulate a very simple circuit (VDC, resistor, probe) it crashed with this:

Reading symbols from /usr/bin/oregano...(no debugging symbols found)...done.

I appear to be unable to locate the source code, otherwise I would attempt to confirm what haninjapan said about compiling from source. I'm not actually on Ubuntu, but amd64 Debian, but this seems to be the same problem I'm having.

Hello all

sorry for the late reply

can you test out the package from my ppa here and confirm that its still persistent?

https://edge.launchpad.net/~bhavi/+archive/crickinfo/+build/1930930/+files/oregano_0.69.1-2ubuntu1_i386.deb

https://edge.launchpad.net/~bhavi/+archive/crickinfo/+build/1930929/+files/oregano_0.69.1-2ubuntu1_amd64.deb

regards

The package from the ppa fixes the problem for me. However, I had to --force depends it to install (seems to depend on packages only available on Maverick), so the question is could the fix be backported to Lucid?

Okay Javier

ll prepare a sru

regards

Hello

here is the sru diff with the fix backported against latest version in maverick

regards

I just backported fix onto my PPA for lucid the debs should be available in a while

regards

Bhavani: karmic and lucid have the same version number, so you need to do 0.69.1-1ubuntu1.10.04.1. I think we should upload SRUs for both releases.

yes stefano,

on it now :)

regards

Bhavani: The karmic patch will need the release in the version number, too

Done stefano

here is the updated karmic sru diff

regards

Accepted oregano into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

I confirm that the package in lucid-proposed fixes the bug (for me at least). Thank you people! ^^

Peter,

I actually left the v-needed tag on purpose, since the karmic-proposed version still needs testing.

Oops, sorry. I saw this come past:

** Tags added: verification-done verification-neededd
** Tags removed: verification-needed

Which put a typo in the verification-neededd tag, and I assumed you intended to remove it.

Ah, thanks. There's a strange Launchpad bug which duplicates the last
character when you press Enter in the tag editor. I keep stumbling
about that.

This bug was fixed in the package oregano - 0.69.1-1ubuntu1.10.04.1

Removing v-done again, to point out that karmic still needs testing.

I'm unable to reproduce the issue in Karmic with the samples shipped with oregano. Could you please attach to this report a sample (non-confidential of course) which is known to make Oregano crash ?
Thanks in advance.

hello jean,

unfortunately m not on a karmic system :(

AFarris01: can you please provide feedback on jean's comment?

also any one on a karmic system can you please test out the proposed package?

with warm regards,

@Jean: In Oregano All I had to do to make to make it crash originally on Karmic was launch oregano, and create a simple circuit with the following: a VDC element, a resistor, a voltage probe, and a ground, connect them all and try to run a simulation. Oregano would immediately crash. I also substituted other simple elements for the resistor such as a capacitor, or inductor, with the same result. I honestly never tried the Oregano samples as I didn't realize they were there.

I no longer have any Karmic systems to test this on, but I can verify that it now works in Lucid and am very happy for that :)

If need be, I can set up a virtual machine to test this in later, but I'd like wait on that since I'm actually low on HD space atm :(

Hope that helps!

SRU verification for Karmic:
I have reproduced the problem with oregano 0.69.1-1ubuntu1 in karmic and have verified that the version of oregano 0.69.1-1ubuntu1.9.10.1 in -proposed fixes the issue.
I've been able to reproduce the original issue on amd64 but not on i386 which didn't crashed.

Marking as verification-done

Thanks all for reporting and testing.
