internal compiler error on NetBSD-6.0_STABLE i386

Hello, I'm trying to build xen-4.2.1 on i386, however it fails with
'internal compiler error' when building tools:

# LD_LIBRARY_PATH=/usr/pkg/lib gmake tools

...

gmake[3]: Entering directory `/opt/tmp/xen-4.2.1/tools/qemu-xen-dir'

I thought it could be due to flaky hardware, so I ran memtest86 and it
didn't show up any issues.

Is anyone else seeing this on i386?
