Description ghamrouni.iptech 2011-12-22 03:31:18 UTC
We are using the embedded Mono runtime in a C++ application. 
Tested on Windows x86 and Mono 2.11 2.10 and 2.10.6

Scripts are executed by mono_runtime_invoke. When an unhanded exception occur in script-space it will be caught automatically :

MonoObject* exception = NULL;
MonoObject* returnObj = mono_runtime_invoke (m_method, m_objectInstance, NULL, &exception);
However, divide by zero exception is not caught and cause an exception in the C++ application !

Example :

int k = 0;
Console.WriteLine(1 / k);

Please provide a minimal test case that shows this issue.

What might be happening is that the C++ host is hijacking the SEH handlers from mono which it depends to catch such errors.

If you can still reproduce with latest mono version, please feel free to reopen the bug. Thank you.
