In the example down below, StackOverflowProtection should be caught righ within the Main and handled there instead of being propagated to runtime. Currently as I understand, mono_handle_exception_internal () while handling a stack overflow, would ignore stack frames until it could safely acquire 64K of stack space (refere free_stack variable) The implication is that for the example down below the catch handler in Main () would be skipped. (Note: The example uses localloc only for inconvenience. localloc could be replaced with a simple Recurse () and the above bug description would still be vaild) using System; class T { public unsafe static void Main () { int size = 10 * 1024 * 1024; // FIXTHIS: while (size != 0) { Console.WriteLine ("Trying " + size + " bytes ..."); try { byte *buf = stackalloc byte[size]; for (int i = 0; i < size; ++i) buf[i] = 0; } catch (Exception e) { Console.WriteLine ("Caught " + e); size /= 2; continue; } Console.WriteLine ("Can stackalloc " + size + " longs"); break; } } } -- Configure bugmail: http://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
