 // Main entry point for a DLL that can be instructed to crash on
 // load or unload by setting an environment variable appropriately.
 //
 // Note: This code has no CRT to lean on, because some versions of the CRT
 //    have a bug whereby they leave dangling state after taking an exception
 //    during DLL_PROCESS_ATTACH. This in turn causes the loading process to
 //    crash on exit. To work around this, this DLL has its entrypoint set
 //    to the DllMain routine and does not link with the CRT.
