As I mentioned in the issue #5156, I met below issue on my Win10+WSL(Ubuntu) env:
The remote debugger (VSCode on Win10, gdb on Ubuntu 18.04 LTS) works well from the beginning of the main() function. But when I step over the code pthread_sigmask(SIG_BLOCK, &new_mask, &old_mask); (src/tools/routed.cpp(289)), below breakpoints can not work and displayed unverified breakpoint.
Then I found that gdb breakpoint need at least SIGTRAP, SIGSTOP to work (Please refer to [how debugger works](http://www.alexonlinux.com/how-debugger-works) for more details), but all signals are blocked in the source code until server initialized done.
In my understanding, block all signals DO NOT make sense for this osrm-routed process. Only several signals (SIGINT, SIGQUIT, SIGTERM) are expected to wait. So I made the change and it works well for me then.
