Please mask versions from [1.25 to 1.26] inclusive, which is now in portage. Main branch few hours ago fixed. There from comment user rustyx commented on 18 Nov 2019. There are some ODR violations in libgrpc++ (master branch); for example client_channel.cc is included in both libgrpc.so and libgrpc++.so. That leads to the same grpc_core::TraceFlag grpc_client_channel_call_trace being constructed twice (notice this=0x7fffff7a07f0 in both traces below), creating a loop in the trace flag chain. Global objects are merged during dynamic loading, but not their initializers, it's a well-known phenomenon (examples: 1, 2, 3, 4). #1 0x00007fffff6e4e24 in grpc_core::TraceFlagList::Add (flag=0x7fffff7a07f0 <grpc_core::grpc_client_channel_call_trace>) at src/core/lib/debug/trace.cc:80 #2 0x00007fffff6e4f01 in grpc_core::TraceFlag::TraceFlag (this=0x7fffff7a07f0 <grpc_core::grpc_client_channel_call_trace>, default_enabled=false, name=0x7fffff288a06 "client_channel_call") at src/core/lib/debug/trace.cc:98 #3 0x00007fffff0816bc in __static_initialization_and_destruction_0 (__initialize_p=1, __priority=65535) at src/core/ext/filters/client_channel/client_channel.cc:100 #4 0x00007fffff0816ed in _GLOBAL__sub_I_client_channel.cc(void) () at src/core/ext/filters/client_channel/client_channel.cc:4046 #5 0x00007fffff7cf37a in call_init (l=<optimized out>, argc=argc@entry=1, argv=argv@entry=0x7ffffffedde8, env=env@entry=0x7ffffffeddf8) at dl-init.c:72 #6 0x00007fffff7cf476 in call_init (env=0x7ffffffeddf8, argv=0x7ffffffedde8, argc=1, l=<optimized out>) at dl-init.c:30 #7 _dl_init (main_map=0x7fffff7e9190, argc=1, argv=0x7ffffffedde8, env=0x7ffffffeddf8) at dl-init.c:119 #8 0x00007fffff7c10ca in _dl_start_user () from /lib64/ld-linux-x86-64.so.2 #9 0x0000000000000001 in ??

Tested by me. Bug explaned: here https://stackoverflow.com/questions/26547454/static-variable-is-initialized-twice Reproducible: Always Steps to Reproduce: 1. Clone example from https://github.com/grpc/grpc/tree/master/examples/cpp/helloworld 2. Build & run via strace & gdb. 3. Program hang in file greeter_server.cc line 60. code line "std::unique_ptr<Server> server(builder.BuildAndStart());" library call ==> BuildAndStart() Actual Results: Infinity loop, cpu 100% Expected Results: Should nice work. version net-libs/grpc-1.24.3 work as expected. versions 1.25 and later do not work. Please hard mask. In main branch patch exist few hours. May be version 1.27 are fixed.
How to fix. Downgrade to =net-libs/grpc-1.24.3 (now in portage)
Fix in main branch here. We are wait new release. https://github.com/grpc/grpc/commit/5a419c65b02b069f4c92623678743a3ddddc53cb
thanks for detailed report! was able to reproduce and confirm backport below working backport to 1.26.0 here https://github.com/grpc/grpc/commit/72351f63fd650cc7acfcd2d0307e8e8e8f777283

Thanks alot, folks!!! Seems like working. As minimum helloworld sample now working))))) Confirm, =net-libs/grpc-1.26-r1 are working. With best wishes - Yuriy.
