I follow the lists locally, in my email client, so I can't provide you a 
URL. The thread was started on 6-23 on the LiveCode Developer List. Here 
is the content of the original post:

---------------(start quote)---------------

The 64 bit LiveCode IDE fails to open for me under openSUSE Leap 42.1. 
It was previously working under openSUSE versions 12.x and 13.x. While 
there was a period when it failed under Tumbleweed (rolling release), it 
works in at least the last two snapshots. Simple standalones work as do 
simple LC Server scripts.

The first few times I tried, the LiveCode splash screen hanged while 
loading the menu bar (the last text displayed) and the process had to be 
killed. Now the splash screen disappears after less than a second.

Here is the tail of the livecode_tools_log:
  Loading Script Editor...
     Enter Script Editor Initialisation
     Leave Script Editor Initialisation
     Loading User Icon Libraries...
     Enter User Libraries Initialisation
     Leave User Libraries Initialisation
     Loading Error Management...
     Enter Errors Initialisation
     Leave Errors Initialisation
     Loading Menu Bar...
     Enter Menus Initialisation
       Trying to get the platform
       Linux

Starting LiveCode from the command line returns this error:
"Error in 
`/home/warren/.runrev/components/livecodecommunity-8.0.2-rc-2.x86_64/livecodecommunity.x86_64': 
free(): invalid next size (fast): 0x0000000004e84a80"

and sends this to stderr:
     "Use of deprecated SAXv1 function setDocumentLocator
     Got SIGIOT"

It's strange that SUSE built on older and newer libs both work while the 
current "main" version does not. Do these errors reveal any useful clues 
as to what might be done to get it working?

The shell prints a backtrace. Would this be helpful to see? Running 
LiveCode through strace using some particular option?

--------------- (end quote)---------------

To clarify the last sentence of the first paragraph of the original 
(copied here from the dev list) post, simple standalones and LiveCode 
Server do work under Leap, it's the IDE that is the problem.

openSUSE is quietly one of the more popular distros and Leap is the 
current "standard" release so it might be a good thing to get this 
figured out. I wonder what LiveCode does just after it gets the 
platform, as it finishes up the menus initialization. I posted the shell 
backtrace at:

<http://warren.ws/lc_cli_output.txt>

It should be noted that if I run the command several times, the 
backtrace will not consistently end with the same lines; sometimes 
aborting with more lines and sometimes fewer.

Thank you for looking at this :)
