Hi Alex,

To make it work on Ubuntu you have to change this line:

sigAction.sa_flags = SA_SIGINFO | SA_ONSTACK;

to:

sigAction.sa_flags = SA_SIGINFO;

Like on MACOS

this part is giving me an error:

          // setup alternate stack
          stack_t ss{
              static_cast<void*>(sAlternateStack),
              SIGSTKSZ,
              0
          };

          if ( sigaltstack( &ss, nullptr ) != 0 )
          {
             err( 1, "sigaltstack" );
          }

while this is stting up properly the sigalt:

          stack_t ss;
          ss.ss_sp = static_cast<void*>(sAlternateStack); //sAlternateStack;
          ss.ss_size = SIGSTKSZ;
          ss.ss_flags = 0; // Use the default flags (usually 0)
          if (sigaltstack(&ss, nullptr) != 0) {
              err(1, "sigaltstack");
          }

Does it make any sense?

Even tough I am getting this log:

I am investinating over it...
