I realise this will be platform specific: is there any way to get a stack trace from an uncaught C++ exception, but from the point at which the exception is thrown?
I have a Windows Structured Exception Handler to catch access violations, etc. and generate a minidump. But of course that won't get called in the event of termination due to an uncaught C++ exception, and so there is no crash dump.
I'm looking for a Windows solution at the moment (no matter how dirty!), but would like to hear about other platforms if possible.
Thanks.
We implemented MiniDumps for unhandled exceptions in our last title using the information from this site:
And to catch the unhandled exceptions on windows have a look at:
SetUnhandledExceptionFilter (http://msdn.microsoft.com/en-us/library/ms680634%28VS.85%29.aspx).
As an aisde, we spent a lot of time experimenting with the different levels of minidump until we settled on one. This proved to be of no real use in real world crashes as we had no idea what they would be at the time the minidumps were implemented. It's very application specific, and also crash specific, so my recommendation is to add the minidump handler as early as possible, it will grow with the project and through QA and it will be a life saver at somepoint (and hopefully out in the real world too).
