xen/i386/machdep.c compiler error

Hi all,

I'm running latest Xen3 code from -current but I have a
problem
building the domU kernel:

/usr/src/sys/arch/xen/i386/machdep.c: In function
'idt_vec_alloc':
/usr/src/sys/arch/xen/i386/machdep.c:2457: internal compiler
error:
Segmentation fault

The kernel is the same than XEN3_DOMU with some options
disabled (COMPAT_*, DEBUG/DIAGNOSTIC, etc).

Any idea?
