Comment 97 for bug 600219

Hi Simon,
I try to reply to your questions.

1. The problem about log. The error message is due to "this" being NULL. Basically, in C++, you do not address member variable at a fixed address, so you need a base pointer for your instance (called "this") and then you offset your variable starting at "this" address. Let's say it is a pointer to a complex data. "log" is a variable in this complex data, so, once you have "this" you may address "log". Since "this" is null, then your offset is wrong and you get segmentation violation. So, the value of "log" is not even found and it might be NULL.

2. About the compiler error. "this" is not an explicit variable that you change in your code. You cannot change it once created. You may create an instance of an object, and you may delete these instances. This is why user code cannot change "this". and this is why it may be a compiler error. I do not have an answer about this happening randomly even when communicating with the same fax-partner.

Of course I might be wrong, but this is my opinion so far.

Bye,
Giuseppe
