[SOLVED] boost::stacktrace on Windows MSVS 2017

I'd like a backtrace when my Windows application crashes. Boost stacktrace looks interesting, and I've played with it a bit in Linux; however, I'm getting a zero result from safe_dump_to() in Windows!

I presume I've made a simple oversight, and I'm hoping someone can help.

I'm using the MSVS2017 compiler with ninja and CMake.

I've built Boost v1.67 built with these flags:

link=static address-model=64 variant=release threading=multi

I ran the tests in boost_1_67_0/libs/stacktrace/test/ to make sure I'd built the library correctly.

Here is my CMake file, note I used -DCMAKE_BUILD_TYPE=RelWithDebInfo:

cmake_minimum_required(VERSION 3.0)

set( target_name stacktrace_test)

# boost
set(Boost_USE_STATIC_LIBS ON)
find_package( Boost REQUIRED COMPONENTS date_time filesystem thread 
system stacktrace_windbg)

add_executable(${target_name} main.cpp)

set_property(TARGET ${target_name} PROPERTY CXX_STANDARD 14 )

target_compile_definitions(${target_name} PUBLIC
  BOOST_ALL_NO_LIB=1   # disable pragama inclusion 
  BOOST_STACKTRACE_LINK=1
  BOOST_STACKTRACE_USE_WINDBG=1
  )
target_include_directories(${target_name} SYSTEM PUBLIC
  ${Boost_INCLUDE_DIRS}
  )
target_link_libraries(${target_name}
  ${Boost_LIBRARIES} # boost
  dbgeng
  ole32
)

Here is my code, based on Boost stactrace's getting started page:

#include <iostream>
#include <signal.h>     // ::signal, ::raise
#include <boost/stacktrace/stacktrace.hpp>
#include <boost/filesystem.hpp>

void handler(int signum)
{
   ::signal(signum, SIG_DFL);
   size_t result = boost::stacktrace::safe_dump_to("./backtrace.dump");
   std::cout << " " << result << std::endl;
   ::raise(SIGABRT);
}

void crash()
{
   abort();
}

int main(int,char**)
{
   ::signal(SIGSEGV, &handler);
   ::signal(SIGABRT, &handler);
   if(boost::filesystem::exists("backtrace.dump"))  // existing stacktrace?
   {
      std::ifstream ifs("backtrace.dump");
      boost::stacktrace::stacktrace st = 
                      boost::stacktrace::stacktrace::from_dump(ifs);
      std::cout << "Stacktrace from prior run:\n" << st << std::endl;
      ifs.close();   // cleanup
      boost::filesystem::remove("backtrace.dump");
      return 0;
   }
   crash();
   return 0;
}

And here is the output from my compilation:

I've reviewed the compilation flags and nothing jumps out at me.

Any help is appreciated! Thank you, SB
