WebRTC crash at line webrtc::PeerConnectionInterface::RTCConfiguration config; for Native Linux application

I'm writing a Native WebRTC application for Linux (Ubuntu), code is crashing at webrtc::PeerConnectionInterface::RTCConfiguration config;

I have below two speculations

  1. I might be messing up with rtc threads, since the same line runs fine in the sample application.
  2. Is there any mistake in the handling of C++ strings. Not sure how it can impact during the declaration of the variable.

Below is the trace:

Even I have observed this issue. This issue happens because by default webrtc is compiled with -D_GLIBCXX_DEBUG(see file build//config/BUILD.GN). If you don't compile your program with this flag you will get issues because this flag causes the vector's implementation to change for spitting out better debugging messages. So if you don't compile your program with this flag the std::vector implemetation will not be consistent and cause segfaults. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53324
