https://bugzilla.novell.com/show_bug.cgi?id=655669#c0 Summary: Weak GCHandle does not work and crashes in multi-AppDomain scenario Classification: Mono Product: Mono: Runtime Version: 2.8.x Platform: x86 OS/Version: RHEL 5 Status: NEW Severity: Critical Priority: P5 - None Component: GC AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] Found By: --- Blocker: --- Created an attachment (id=401926) --> (http://bugzilla.novell.com/attachment.cgi?id=401926) Sample project to repro the bug 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 create an object in a *secondary* appdomain, allocate a *weak* GCHandle pointing to it and store its IntPtr value somewhere, then later on when I try to to use GCHandle.FromIntPtr to get a GCHandle instance from the stored IntPtr value, CLR runtime will give me an exception. This does not happen to Microsoft CLR and does not happen to *normal* and *pinned* GCHandle on MONO. Reproducible: Always Steps to Reproduce: 1. Unzip attached project and use xbuild to build the solution. 2. In the generated bin folder, run "mono DefaultAppDomainApp.exe" Actual Results: An exception is thrown out saying: Unhandled Exception: System.ArgumentException: GCHandle value belongs to a different domain Server stack trace: at System.Runtime.InteropServices.GCHandle.op_Explicit (IntPtr value) [0x00000] in <filename unknown>:0 at System.Runtime.InteropServices.GCHandle.FromIntPtr (IntPtr value) [0x00000] in <filename unknown>:0 at SecondaryAppDomainApp.Program.Main (System.String[] args) [0x00000] in <filename unknown>:0 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. _______________________________________________ mono-bugs maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-bugs
