Example provider application with EMA C++ is crashing at exit

RTSDK-2.0.6.L1.linux.rrg

RTSDK-2.0.6.L1.linux.rrg/Cpp-C/Ema/Executables/CENTOS7_64_GCC482/Optimized/IProv280

Provider crashes at end with stack

To reproduce

-Start provider with MALLOC_CHECK_=2

- Start consumer e.g. RTSDK-2.0.6.L1.linux.rrg/Cpp-C/Ema/Executables/CENTOS7_64_GCC482/Optimized/Cons331

- After consumer receives a message, kill consumer

- Kill provider with control-C, the provider crashes with above stack

Hello @makarand.vaidya ,

My understanding is that the crash happens consistently on your side, and is reproducible repeatedly.

I was not able to directly reproduce the crush on my side: i have followed the instructions given, and on my side, IProv280 has exited cleanly.

I have also tried the same test on windows RTSDK, and also the provider has exited cleanly.

In this situation, the best approach, in my understanding, is to open a Premium Support case, and to investigate the issue in detail, by trying to match the environment that you run and try to reproduce on such- mine is on docker, and the versions of installed libraries, likely differ from yours.

My record indicates that you are a named premium support user for your organization, if this is the case, you can open a premium support case directly, from Refinitiv Real Time API documentation area on developers portal.
