Andrew,
So do you want to say this is not a bug? I know the class isn't intersting
but I think it shouldn't have size equal to 0.
Thanks,

Attached (gzipped) fbmmx.i (from Xorg 6.8.2 xc/programs/Xserver/fb/fbmmx.c)
gives "fbmmx.c:871: internal compiler error: in push_reload, at reload.c:1303"
when compiled with 4.1.1 on i686-linux-gnu. This is probably a regression as
I've previously compiled the same Xorg release fine with 4.1.0.

A third-party library I'm using doesn't compile with gcc 4.1.1 anymore (it
still did with 4.0). The problem is that some header files contain a code
fragment (I've stripped it down) like this:

template class I {
public:
int size;
};

gfortran fails with an internal error when the attached file is compiled with
-O3 optimization:
error: edge from 62 to 64 should not be marked irreducible
error: basic block 64 should not be marked irreducible
error: edge from 64 to 53 should not be marked irreducible

This is a bug specific to Debian's GCC. There is no such ICE in the whole of
