Hi, thank you all very much for your replies.
@Hartmut I did add the code you suggested and the result is the same as before. @Praveen, Thomas I am using Ubuntu 17.04 with gcc 6.3.0. I did try it with disabled stack protector with a new clean build and get the same result as before. make VERBOSE=1 shows me that the compiler gets called with the flag (/usr/bin/c++ -g -fno-stack-protector -Wall .....) for Container and main so it should be disabled. I did look again at the hello_world_component example and the hello.sh bash script that compiles it. The -fno-stack-protector flag is not set and it compiles and runs without a problem on my machine. So if its the gcc stack protection shouldn't it fail too? The only differences i see between the example and my code is that the example uses a struct and i am using a class. Also the example uses typedef while i am using "using" as stated in the docu <http://stellar-group.github.io/hpx/docs/html/hpx/manual/components/components_client.html> Best Regards, Tobias On 2 June 2017 at 08:06, Thomas Heller <thom.hel...@gmail.com> wrote: > Hi Tobias, > > On Donnerstag, 1.
