Springlobby crashes with "*** Caught unhandled unknown exception; terminating"

Post by aleksey » 04 Mar 2016, 01:57

I recently upgraded from Ubuntu 15.04 to 15.10, and springlobby stopped working. It crashes with the message "*** Caught unhandled unknown exception; terminating" immediately after I run the command.

The version of the lobby does not seem to matter. I tried version 0.224, which comes with Ubuntu, and it crashes. I also compiled version 0.243 on my own, and it crashes with the same message.

I renamed the dirs "~/.spring", "~/.springlobby", and "~/.config/spring", because I thought something in them might cause the problem. This did not fix it.

Running "springlobby -cl -l 5" gives:
Message /home/aleksey/Downloads/springlobby-0.243/src/springlobbyapp.cpp:119 SpringLobby 0.243 started
*** Caught unhandled unknown exception; terminating

or, "/usr/games/springlobby -cl -l 5", gives:
Message: SpringLobby 0.224 started
*** Caught unhandled unknown exception; terminating


If I can assist in any way (by running some debugging commands, or listing the versions of the libraries I have installed, or whatever), I will be happy to do it. I will monitor this post frequently. Please help, I really miss my favourite game.

Thanks.

can you start with springlobby -

can you please run your self-compiled version with:

Code: Select all

gdb springlobby
run
and after it crashes:

Code: Select all

bt
which should give a backtrace with source filenames / line numbers and copy/paste the output? (ideally at paste.springfiles.com or sth. similar)

To follow up on that, is there a way to re-compile spring lobby with debugging symbols on? Or are they on by default? Or, is it not the issue?

it shows no issue because springlobby doesn't crash, it quits because of the unhandled exception.

to get a stacktrace

Code: Select all

gdb springlobby
catch throw
run
this will stop on all exceptions. possible there are some exceptions before the unhandled exception, sorry can't give very good instructions.
maybe "catch exception unhandled" works as excepted. you can verify by running multiple times, just type "cont" to make the program continue / or run when it quit.

when gdb stopped at the correct place, type "bt" to get a backtrace.


to change the buildtype edit CMakeCache.txt and set CMAKE_BUILD_TYPE to DEBUG

I recompiled with CMAKE_BUILD_TYPE=DEBUG.

I noticed this: "#1 0x0000000000aadcaa in LSL::_LoadLibrary (libpath="/usr/local/lib/libunitsync.so")..."
There is indeed libunitsync.so file there. It's dated Nov. 29, 2014.

I removed that file, and the lobby launched ok.
Then I moved ~/.spring/ directory back (I renamed it earlier, because I thought it might be causing problems), and tried again:

This time, I noticed this line:
#8 0x00007fffe00b1f63 in ?? () from /home/aleksey/.spring/engine/100.0.1-1218-gdc0df52 develop/libunitsync.so

I removed that engine dir from /home/aleksey/.spring/engine/. Then I tried again.

Without pasting the whole thing, the next offender was the 101.0 engine:
#8 0x00007fffe00b1f63 in ?? () from /home/aleksey/.spring/engine/101.0/libunitsync.so

Again, I removed that engine dir, and now springlobby launched ok.

When I joined a battleroom and pressed Start to spectate an ongoing battle, nothing happened.
In the terminal window, I saw that it was trying to use /usr/local/bin/spring, and could not find boost 1.55 libraries (I have 1.58 installed now).
I still had a very old version of the spring engine installed there, probably 94 or something, from the time before the lobby supported multiple engines, and spring stored them each in its own directory. So, I removed that old engine, and everything seems to work now!

Thank you for you help!

very likely thats the same issue as https://springrts.com/mantis/view.php?id=5050

i was just confused by the "caught unhandled exception" as i got "free(): invalid pointer"

I had this issue also when I installed 101 via SL. The glibc abi change does seem a viable explanation
