* Assertions and pointer violations in debug mode may trigger a dialog
|
|
* on Windows. When running headless this is not helpful, but
|
|
* unfortunately it cannot be disabled with a compiler option so code
|
|
* must be injected into the runtime early in the main function.
|
|
* A call to the provided `init_headless_crt()` macro does this in
|
|
* a portable manner.
