tool build failure

[Malcolm Herbert <mjch%mjch.net@localhost>]

Building -current on a 5.99.15 host from sources of last night (.au time)
fails with:

|#       lex  asn1_compile/lex.c
|/usr/src/obj/tooldir.NetBSD-5.99.15-i386/bin/nblex    -olex.c 
/usr/src/crypto/dist/heimdal/lib/asn1/lex.l
|nblex: fatal internal error, exec failed
|  
|*** Failed target:  lex.c
|*** Failed command: /usr/src/obj/tooldir.NetBSD-5.99.15-i386/bin/nblex -olex.c 
/usr/src/crypto/dist/heimdal/lib/asn1/lex.l
|*** Error code 141
|  
|Stop.
|nbmake: stopped in /usr/src/tools/asn1_compile

... not sure whether that's a problem with the source that nblex was
working on, or a problem with nblex itself ... any pointers?
