how to simply create a C++ stacktrace dump on crash on windows

Question

I'm not looking for anything other than logging a stacktrace to a file when the program crashes. I don't care for it to email me or upload anything to a server. It's fine for the moment if that means it only works for RelWithDebInfo builds, or for builds with access to .pdb files or whatever. How can I accomplish this?

Answer 1

You can use MiniDumpWriteDump from dbghelp.dll.

Use Ian Taylor's libbacktrace .

It is ported to several OSes. On Linux, it works better if executables and libraries are compiled with DWARF debug information. (eg with g++ -Wall -g -O2 if using recent GCC ). Be also aware of signal(7) and signal-safety(7) on Linux.

RefPerSys uses it. And so does recent GCC compilers in 2021.
