NetBSD 10 earmv5 issue with awk

[John Klos <john%klos.com@localhost>]

Hi,

I'm in the process of updating some PogoPlugs that've been running 
amazingly well since the NetBSD 7 days. PogoPlugs use the Marvell Kirkwood 
earmv5 CPU.

The first test upgrade went well and everything works perfectly, so far, 
except awk.

When compiling pkgsrc/pkgtools/pkg_install, awk failed making depends:

...
of variables in the first group before continuing.  Be sure to run
`/usr/bin/make clean' after the changes.
==========================================================================
[1]   Segmentation fault (core dumped) ${AWK} -f 
${PKGSRCDIR}/mk/pkgformat/pkg/reduce...
*** Error code 1

gdb gives:

Program terminated with signal SIGSEGV, Segmentation fault.
#0  0x0001d26c in yycheck ()

So I compiled awk with symbols and tried again, and awk failed like so:

assertion "s < f->state_count" failed: file 
"/usr/src/external/historical/nawk/bin/../dist/b.c", line 568, function "pmatch"
[1]   Abort trap (core dumped) ${AWK} -f 
${PKGSRCDIR}/mk/pkgformat/pkg/reduce...

Any ideas why this is happening? If it gives a clue, I think I saw this 
when updating a PogoPlug a year ago, so I just compiled NetBSD for earmv4 
and used that.

Thanks,
John
