GUI 线程中的异常导致 vshost.exe 崩溃

Question

I think my Visual Studio 2008 (.net 3.5) is corrupted.

If I start a new Windows Forms project in a new solution, add the code

double[] x = new double[2];
x[3] = -1.0;

to the form_load handler (or a button handler), and try to debug the program, it crashes immediately, not throwing an exception, but actually crashing.

If I put the same code in the form constructor or in Main, an exception gets thrown like normal.

Any ideas what might be going on?

Don't worry, your VS is fine.

The form load handler will (ultimately) be invoked from the Windows message loop, where exception handling is a little different. See here for more details.
