internal compiler error heimdal

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

With today's source, I don't seem to able to get past:

# pwd
/usr/src/crypto/external/bsd/heimdal/lib/libvers
# make dependall
#   compile  libvers/make-print-version.lo
cc -O  -DHAVE_IPV6 -DHAVE_CONFIG_H -I/usr/src/crypto/external/bsd/heimdal/include -DHAVE_CONFIG_H -c -o make-print-version.lo.o    /usr/src/crypto/external/bsd/heimdal/dist/lib/vers/make-print-version.c
cc: internal compiler error: Segmentation fault (program as received signal 11)

*** Error code 4

Started with an empty /usr/obj, and sh build.sh -E build

# ls obj.amd64/
as.core                   make-print-version.lo.o

Zapping /usr/obj insufficient?
