Unfortunately, in looking at the dump, gg was unable to get enough
information to determine the cause.

I noticed that in previous dumps you sent, you were logged in as root so
the dump is complete but this time as* jora:*
    ** segv at 0x7f951061192d in pid 8185, tid 9135
    created on Tue May  8 00:22:36 2018
            by 1000:1000 *jora*(jora,,none,none,)

So in the end the dump process has an issue as in the bottom of the dmp
file which makes it incomplete:





*   Could not attach to process.  If your uid matches the uid of the
target   process, check the setting of /proc/sys/kernel/yama/ptrace_scope,
or try   again as the root user.*
If you run as a user, you can still get almost as good a dump using the
following procedure

*.-------------------------------------------------------------------------------------------------------------------------------*















*For those who can not run as root or can not create the problem while
running as root, another methodto create a dump is available. Here are the
steps to do so:1) Temporarily login as root and keyin: echo 0 >
/proc/sys/kernel/yama/ptrace_scope  This opens up ptrace, used by gdb (the
debugger). You will want to reverse this when done.2) Run cinelerra as an
ordinary user from a terminal window using the command line and try to
create   the problem. If the program crashes, this should produce a file
named /tmp/cinelerra*.dmp where *   is a number. The dump usually takes
about 30 seconds or so to complete after the failure invokes the   crash
handler so be patient.3) Email the output that shows in the terminal window
from where you started up cin5 and upload or   directly email the
/tmp/cinelerra*.dmp file (this file is too large for the Mailing List).4)
After you are finished creating/testing the problem, reverse the previous
setting while logged in as   root by keying in: echo 1 >
/proc/.../ptrace_scope .*
-----------------------------------------------------------------------------------------------------------------------------

If you can easily reproduce the SEGV or if it happens again, or if you have
an exact set of steps that
creates the problem so we can reproduce here, please send another dmp so we
can fix it!!
Thank you, Phyllis
