Description-
I source build igniton fortress and it works fine in simple worlds but crashes with models and complex worlds like auv_controls.sdf.I also tried citadel source build and faced same error.Then I tried binary build with docker and it worked but when I source something from my main os into docker and then try to run same world crashes(same error).I thought it could be clashing with some of my libraries hence I reinstalled Ubuntu and tried it in clean OS but faced same error.I have been facing this error from a good many days and I tried asking it on http://answers.gazebosim.org but got no reply. Any help will be much appreciated

Steps to reproduce
ign gazebo auv_controls.sdf
Output-

Complete Log-
ign gazebo auv_controls.sdf -v4.log

Hey @harshmahesheka which version of GCC are you using. This looks like an issue with the std::filesystem and segfault. Looks similar to gazebo-tooling/release-tools#639 .

Hey, @arjo129 I am using gcc (Ubuntu 8.4.0-3ubuntu2) 8.4.0.
Also I tried changes you did in #1346 and gazebosim/gz-common#312 but insted of https://github.com/ignitionrobotics/ign-common/blob/9d0b0683030b96b7042d46de491aa1171693a9ed/src/Filesystem.cc#L77 I used

 if (ignition::common::absPath(_path)==_path)
   return false;
 else 
   return true; 

as std::filesystem is not used here in ignition fortress and everything works.Thanks for the help

You might want to use GCC 9 for everything then the std::filesystem issue should go away without code changes.
