Description Creme Brulee 2020-10-30 04:26:49 UTC

Description of problem:

psi-plus crashes when you try to connect to a server (change the status from offline to online).

Version-Release number of selected component (if applicable):
1.4.1515

How reproducible:
Always

Steps to Reproduce:
1. run psi-plus (should be enough)

In case you don't automatically connect to a server, do so manually by changing your status to online (you need to have an account, if you don't, create it first)


Actual results:
a crash occurs

Expected results:
you're successfully connected and see your roster populated with contacts (assuming you have them).

Additional info:
I built psi-plus from sources of the latest snapshot and it works like a charm.
v.1.4.1523
I used cmake to build it.

Hello Vitaly
Thank you for your reply.
I've installed psi-plus-1.4.1523-1.fc33 but I get the same error.

Comment 5 Vitaly 2020-10-31 09:41:16 UTC

> This error doesn't occur when I run psi-plus of the same version built manually

I guess because your build doesn't use Fedora build flags.

I think this crash is related to LTO enabled by default. I will try to rebuild without LTO.

Comment 6 Vitaly 2020-10-31 09:51:42 UTC

Please try psi-plus-1.4.1526-1.fc33. I built it with disabled LTO.
