I am trying use boost stacktrace to get a stack dump when my program encounters an unhandled exception under windows. I have installed a signal handler as described in the stacktrace documentation, and it gets called. However, the resulting stack trace is after everything has been unwound. For example, when I force a failure by dereferenceing a null pointer many levels down in my function hierarchy, the stack trace shows: 0# boost::stacktrace::detail::this_thread_frames::safe_dump_to_impl<char const *> at f:\home\tools\boost\boost\stacktrace\safe_dump_to.hpp:68 1# boost::stacktrace::safe_dump_to at f:\home\tools\boost\boost\stacktrace\safe_dump_to.hpp:120 2# my_signal_handler at f:\home\test\main.cpp:233 3# 0x5171407B 4# my_signal_handler at f:\home\test\main.cpp:235 5# 0x51713883 6# __tmainCRTStartup at f:\dd\vctools\crt_bld\self_x86\crt\src\crtexe.c:603 7# WinMainCRTStartup at f:\dd\vctools\crt_bld\self_x86\crt\src\crtexe.c:403 8# BaseThreadInitThunk in kernel32 9# RtlInitializeExceptionChain in ntdll 10# RtlInitializeExceptionChain in ntdll This is not particularly helpful, of course -- I want to know the call stack at the point of the failure. Is there any way to get that? What am I missing? Thanks, Don
