I'm new to ASAN and ran into a situation running C++ program after
compiling in -fsanitize=address to investigate a segfault that happens
after running an hour or so.
compiling a x64 C++17 with gcc 8.4.0 under ubuntu 18.04.1
The program doesn't actually try to allocate 1.8 petabytes, as it starts up
and runs properly on my desktop computer for a while without ASAN compiled
in. With ASAN, i get the stack below immediately on startup:
Any known issues with gRPC? I realize this is not much context at all, but
would appreciate suggestions on how to proceed at this point.
I might add that my first try was to run the program under valgrind to see
if i could catch the segfault, but valgrind exits with an unknown
instruction while executing the code prior to entering main()
