illegal instruction #299

Hello,

Probably a null pointer lost somewhere. Random appearance. Can start sometime, asking 'I agree license', display show list, then bang !

no interest on tracking a SIGILL signal ?

you know this kind of thing is never good and should not happen !

at least give me symbols to make gdb happier.........

Can you try another version, an actual build or even an old build?

Franck78 commented 7 years ago

well, I didn't uninstall 3.9 ;-) It never had a sigill. Continuing using it on my Opensuse 13.2.

What are you calling 'actual build' ? You want me to build it on my machine ?

On an Ubuntu (14.04 or 16.04 not sure), no sigill.

VitorVRS commented 7 years ago

Here we have all builds: https://ci.popcorntime.sh/view/All/job/Popcorn-Time-Desktop/

From 3.9 to 3.10, nodewebkit was updated, have you tried to search if there are issues with your OS and nodewebkit?

Franck78 commented 7 years ago

Perhaps related to #298 ? It's difficult to track for me. Who doest what... who is who libnw.so is webkit (recent) compiled by you (not patched), and you think on Opensuse it have problems ?

I don't find a package with full debug info in Jenkins. And since Mars (3.9) you added lot of modification !

Given the reaction on my system, it looks like a return function is not checked ? Using somewhere after a bad pointer. Because the code is 'executed', maybe a thread ? gdb Pop310 shows plenty of thread launched during startup. It fails very often before asking 'license agreement'.

An old database is not the problem because I tried on a clean account.

What is happening during the init phase, problem is here.

I think this bug will stay for the posterity... Something wrong somewhere.

Anyway, I will upgrade my still supported not so old opensuse 13.2 to LEAP_42. No more siggill. During a short period starting right now, I have the two systems up and running. If someone interested in putting a name on the culprit component.
