log of crashing Xorg

Trying to use xrdp with the xorgxrdp driver, the X server segfaults on startup.

I'm attaching the full log just in case.
Comment 1 Koichiro Iwao freebsd_committer 2019-06-21 08:03:57 UTC
Is it installed by pkg? built from ports?
Comment 2 Felix Palmen 2019-06-21 08:15:35 UTC
It's built from ports using poudriere. No special options are set, but I have a global

DEFAULT_VERSIONS+= ssl=libressl samba=4.8 php=7.2 pgsql=10 linux=c7
Comment 3 Felix Palmen 2019-06-21 08:28:46 UTC
I now tried building with

x11-drivers_xorgxrdp_SET+=	DEBUG

but the stacktrace gets worse:

[3159592.537] (EE) Backtrace:

Do I need to build any other packages with debugging as well to get a meaningful stacktrace here?
Comment 4 Koichiro Iwao freebsd_committer 2019-06-23 02:26:10 UTC
(In reply to Felix Palmen from comment #3)
Yes, the stacktrace is not helpful yet.
Comment 5 Felix Palmen 2019-06-23 07:52:08 UTC
(In reply to Koichiro Iwao from comment #4)
I see that of course ;) Any hint how I could get a useful one? Enabling DEBUG on xorgxrdp made it worse (not even showing filenames any more), and x11-servers/xorg-server doesn't have a DEBUG knob. Am I looking in the wrong place?
Comment 6 Koichiro Iwao freebsd_committer 2019-08-09 01:58:13 UTC
(In reply to Felix Palmen from comment #5)
Can you confirm if your issue is identical to reported to upstream?

Comment 7 Koichiro Iwao freebsd_committer 2019-08-20 04:59:25 UTC
Let me know the issue still occurs with xorgxrdp 0.2.11 or later.

Unfortunately, yes, it's still crashing.

Comment 9 Koichiro Iwao freebsd_committer 2019-08-21 23:13:52 UTC
Reopen.
Comment 10 Felix Palmen 2019-08-22 07:54:50 UTC
Any idea how to move forward here? Should I better report it upstream? I still don't get a meaningful stacktrace though ...
Comment 11 Koichiro Iwao freebsd_committer 2019-08-22 08:07:20 UTC
(In reply to Felix Palmen from comment #10)
I am one of upstream developer so there will be no luck ¯\_(ツ)_/¯
But for the record and to let other upstream developers know, can you raise a issue to upstream?
