CoppeliaSim crashes during license validation on Ubuntu 20.04

Post by wata »

Hello,

When I try to start Pro version with a dongle on my desktop pc (Ubuntu 20.04), it crashes in the process of license validation. And an error message comes up as follows:

Code: Select all

$ ./coppeliaSim.sh
[CoppeliaSimClient]    loading the CoppeliaSim library...
[CoppeliaSimClient]    done.
[CoppeliaSimClient:loadinfo]   launching CoppeliaSim...
[CoppeliaSim:loadinfo]   CoppeliaSim V4.2.0., (rev. 5), flavor: 2
free(): double free detected in tcache 2
/coppeliaSim.sh: line 35: 789335 Aborted          (core dumped) "$dirname/$appname" "${PARAMETERS[@]}"
Previously, it worked correctly on the machine. Reinstallation didn't solve the problem.
If I do the same thing without a dongle, it successfully starts as an evaluation version.
Besides, the dongle still works with other Ubuntu 20.04 machines.

Do you have any ideas on this issue?

Thank you.

Hello,

can you remember what you did between the moment when it worked, and the moment it stopped working? Also, you can try to change keepDongleOpen to true in system/usrset.txt

Cheers

Thank you for the quick reply.

As for the cause, it had been a few days since I had last used it, so I have no good idea.
But, as you suggested, changing keepDongleOpen from false to true in system/usrset.txt solved the problem.

Thank you so much!
