I have a bunch of unit tests that I'm running in batch mode. Occasionally, one will crash with a debug assertion fired from the Visual C++ library. This causes a dialog to pop up, and the unit tests stop running until I click "OK" to close the dialog.
How can I make a C++ program just crash (like on Linux) when it hits an assertion, instead of popping up the annoying dialog?
Note: I do not want to disable assertions; just the dialog.
Check out _CrtSetReportHook():

MSDN advertises this as a robust way for an application to handle CRT runtime failures like assertions. Presumably you can define a report hook that dumps your process:
This code will disable display of dialog. Instead, it will print an error in the output window, and stderr.
int main( int argc, char **argv )
{
if( !IsDebuggerPresent() )
{
_CrtSetReportMode( _CRT_ASSERT, _CRTDBG_MODE_FILE | _CRTDBG_MODE_DEBUG );
_CrtSetReportFile( _CRT_ASSERT, _CRTDBG_FILE_STDERR );
}
...
}
The same must be applied for _CRT_ERROR if you use Q_ASSERT from Qt library.
I put the code for a suitable hook (that you can install with _CrtSetReportHook()) in: https://stackoverflow.com/a/28852798/2345997
