internal compiler error: in build_call, at cp/call.c:323

Can't narrow it down - happens in five different places in our codebase.

Mark, this appeared with your patch
http://gcc.gnu.org/ml/gcc-cvs/2005-10/msg00056.html

Looks like a latent bug, though.

BTW, the code compiles with a function reference instead of a function pointer
as template parameter.

I actually disagree with saying the compiler you are using is a 4.0.2 compiler.
 It is a 4.0.3 compiler from the date you gave in comment #3.

This is not the official FSF 4.0.2 release.
Redhat's 4.0.2-8 version contains some patches from the 4.0.3 release.
Even their gcc.info file says so:

  This manual documents how to use the GNU compilers, as well as their
  features and incompatibilities, and how to report bugs.  It corresponds
  to GCC version 4.0.3.  The internals of the GNU compilers, including
                ^^^^^^^
