https://bugzilla.novell.com/show_bug.cgi?id=655674#c0 Summary: Got exception and program crashes when LayoutKind.Auto is used during P/Invoke Classification: Mono Product: Mono: Runtime Version: 2.8.x Platform: x86 OS/Version: RHEL 5 Status: NEW Severity: Critical Priority: P5 - None Component: interop AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] Found By: --- Blocker: --- User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; InfoPath.2; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729) If I creat a class and mark it as [StructLayout(LayoutKind.Auto)], and pass its instance from managed code to native code using P/Invoke, runtime will report an exception saying classes being passed to native side must be marked with StructLayout attribute. LayoutKind.Auto works on Microsoft .NET platform. Is it by design MONO does not support it? Reproducible: Always Steps to Reproduce: 1. Create a class A and mark it as [StructLayout(LayoutKind.Auto)] 2. Create a P/Invoke managed method like: static extern void Test(A a) in managed code. 3. Create a corresponding native function like void Test(void *a) 4. In managed code, call the method created in step 2 Actual Results: Exception is thrown out saying classes being passed to native side must be marked with StructLayout attribute. Expected Results: No exception. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
