I was encountering the same warnings with the 6.2 version of the C++
compiler. I believe it is a problem with the compiler/linker and not
Performer. I have not returned to address this problem, but this is the last
thing I sent to SGI:

> If the class in question has a non-initialized const member variable and no
> default constructor defined the compiler apparently creates a default
> constructor that the linker is complaining about.

Note I only got this with the N32/64 versions of the linker (ld32 and ld64).
I have not tested under different configurations (like with the 7.0
compilers).

This warnings went away when I added a default constructor to the classes it
was complaining about (__TID_#x seems to be the "mangled" name for the default
constructor of class x). I made it empty and put it in the private section
where it could not be accessed.

Can a C++ guru explain this behaviour (the warnings, not the fact that I
didn't want a default constructor :-)?
