Steam html5app player segfaults with STEAM_RUNTIME=0

[Oxalin]

I've been trying to make it work for some time now, but whenever I launch Steam with STEAM_RUNTIME=0 (while this works), I'm unable to view videos in my library. I'm not talking about the teasers in the store, but the real full video under Library->Videos.

Let's use "Kung Fury" as an example. Here is what I get in a terminal: Game update: AppID 374570 "Kung Fury", ProcID 15450, IP 0.0.0.0:0 ERROR: ld.so: object '/home/ademers/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

However, when using STEAM_RUNTIME=1 (with some tweaks since I use AMD's open source driver, such as removing libstdc++...), it works fine.

Yesterday, I tried to debug html5app_steam with gdb. However, symbols are missing. Would it be possible to get them? Or to have a debug compiled html5app_steam?

I'm using today's latest Steam test version on ArchLinux 64.

[gdrewb-valve]

I believe the app is just a wrapper around core Steam services so you'd need a debug version of Steam. I don't think there are any plans to release something like that.

[Oxalin]

Well, that could be usefull for Valve at some point and for us to give you a better hand.

Anyway, I'll try to remove libraries one at a time from steam-runtime until I get the same crash.

That being said, is there a better way of identifying the source of the crash? Maybe Valve could add some debug output or be more verbose?

[gdrewb-valve]

The Steam team will take a look at this, they may add something.

I was lucky to query a dmesg for some other reason after trying to launch a movie with STEAM_RUNTIME=0. I found this a segfault related to libudev.so.0.13.1: [ 837.321419] html5app_steam[17113]: segfault at 73656375 ip 00000000f1c74449 sp 00000000ffe5acd0 error 4 in libudev.so.0.13.1[f1c71000+10000] [ 842.325318] html5app_steam[17149]: segfault at 73656375 ip 00000000f1c5c449 sp 00000000ffd012b0 error 4 in libudev.so.0.13.1[f1c59000+10000] [ 851.657851] html5app_steam[17189]: segfault at 73656375 ip 00000000f1c5c449 sp 00000000ffe37cb0 error 4 in libudev.so.0.13.1[f1c59000+10000]

Just in case, I created a symlink to the Steam-runtime libudev next to html5app_steam. However, even if html5app_steam uses steam-runtime libudev version with this trick, it crashes in the same way.

[Oxalin]

I've been able to fix the problem by removing libgcrypt15 package (and steam-libs) after removing libgpg-error.so* from Steam's folder.

However the proposition for a debug version of Steam or something similar would still be a great idea.

[Oxalin]

Well, it seems to be something else after all: it worked correctly until I restarted... Investigating

[Oxalin]

It seems it was just "luck": I'm able to launch the player from time to time (once every 10 to 20 times). Most often, it works if I quickly try launching it after starting Steam and connecting (but it can work at any other time, it just happens more often).

I would be tempted to think there is really a bug lurking somewhere around the html5app_steam player that is revealed once STEAM_RUNTIME is turned off.

[Oxalin]

Here is a new log where at first it wouldn't allow playing a movie, but after a couple of launches, it worked. Nothing special can be seen from comparing when it works from when it doesn't, but it may give your team a clue where to look. I removed some warnings that are related to fontconfig and some "Mesa: User error: GL_INVALID_ENUM in glMatrixMode(mode)" irrelevant to the bug:

Tested once again today and everything seems fine (after a few tests). This bug can be closes for now.
