General protection fault ip

[francoism90]

traps: gerbera[242601] general protection fault ip:7ff6df6418c2 sp:7ff6c7ffde98 error:0 in libupnp.so.13.1.0[7ff6df62d000+1c000]

This happens after updating Gerbera to support the latest support libupnp. Note: I'm using the use ipv6 switch.

That is not nice... Can you get a traceback at all? Try running Gerbera under gdb and run bt when it crashes out, it looks like something is going wrong in libupnp.

Please post that along with an error log at debug level, thanks!

I see the same with upnpn 1.10 and gerbera 1.3.4
Of course the crash come from upnp

@whyman It doesn't crash when downgrading libupnp 1.8.5 to 1.8.4 and recompiling Gerbera.
I'll try to provide a crash dump later this week.

[KarlStraussberger]

The issue can be solved in libpupnp by a fix https://github.com/mrjimenez/pupnp/pull/122

[whyman]

@KarlStraussberger Thanks for the patch!

I've replicated the issue with both 1.8.5 and 1.10.0 😞

But the above patch fixes the issue, so we just need to wait for the new versions

[marillat]

Fixed for me in linupnp 1.10.1
Thanks to @KarlStraussberger for the patch

[whyman]

Lets close this then, resolved with 1.8.6 and 1.10.1
