Errors integrating quiche application with ns-3 DCE 1.12

[Harsh Patel]

Hi all, 

I am integrating ns-3 DCE 1.12 on an Ubuntu 20.04 system. I have build quiche code and am currently trying to set up a ns-3 DCE example to work with quic. To integrate quic with DCE, I have to make the examples in the quiche/quiche/examples directory and set that path in the DCE_PATH environment. After that DCE is able to detect the executable and try to use it. I have attached the code file which is used to run the ns-3 DCE example for your reference. 

When I run the example, I get the following error: 

ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.

To fix this, I run the following command:
export LD_PRELOAD=$(gcc -print-file-name=libasan.so)

After that, I run into this error:

You are trying to dlopen a elf-cache/0/libc-ns3.so shared library with RTLD_DEEPBIND flag which is incompatible with sanitizer runtime (see https://github.com/google/sanitizers/issues/611 for details). If you want to run elf-cache/0/libc-ns3.so library under sanitizers please remove RTLD_DEEPBIND from dlopen flags.
[I am also getting memory leak errors with the errors above. Here is how that looks like: ]
==365346==ERROR: LeakSanitizer: detected memory leaks

... A list of direct and indirect memory leaks ... 

I have tried a few things I found online but I am not able to find a solution/workaround. Is there a way I can remove the RTLD_DEEPBIND from dlopen flags?   

Thanks & Regards,
