m_pMethTab can be NULL in a very small window between the time object is allocated in GC heap and its method table is set. Check FastAllocateObject in gcscan.cpp - the window I am talking about is between Alloc and SetMethodTable.
m_pMethTab of Object* should be correctly setup all the time otherwise. -Jan This posting is provided "AS IS" with no warranties, and confers no rights. -----Original Message----- From: Discussion of the Rotor Shared Source CLI implementation [mailto:[EMAIL PROTECTED] On Behalf Of Chris Tavares Sent: Sunday, August 10, 2003 1:47 PM To: [EMAIL PROTECTED] Subject: Re: [DOTNET-ROTOR] !GCForbidden assertion: why? Jan, Thanks, you hit the nail on the head - it was a null pointer reference. Found that one and fixed it. However, I've hit another snag that's a little more complicated. In general, under what circumstances can you have an Object * where m_pMethTab is null? I'm hitting that - it's apparently getting to my assertion via EEClass::RunClassInit. Is the method table not yet set up at that point?
