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 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
