When you report a bug, or any other difficulty with gcc, please report the
full text of any error messages you recevied.
Next time, see http://gcc.gnu.org/bugs.html before reporting a bug.

It seems like a basic C++ question; it should have been asked in
comp.lang.c++.moderated, or a similar forum.

I cannot tell if this is legal C++; your 'code snippet' leaves out too
much.
If 'function' is a namespace, it is definitly not legal.
If 'function' is a class, and there is also a function declared as
'void* function(void*)' (legal, but bad practice), it will compile, but
it may not do what you expect.
Note that function pointers and member function pointers are very
different beasts, and pthread_create() wants a function pointer.
