On my NetBSD i386-current with pkgsrc-current I see this:

===> lars@glengoyne:/usr/pkgsrc/net/openslp %make install
===> do-shlib-handling [openslp-1.2.1] ===> [Automatic ELF shared object handling]
===> register-pkg [openslp-1.2.1] ===> Registering installation for openslp-1.2.1
[1]   Segmentation fault (core dumped) /home/lars/tmp/p...
===> check-wrkref [openslp-1.2.1] ===> Checking for work-directory references in openslp-1.2.1

-rw-r--r--  1 root  wheel  0 Oct 24 21:47 work.glengoyne/.pkgdb/+CONTENTS
===> lars@glengoyne:/usr/pkgsrc/net/openslp %

i.e. 'make install' silently fails leaving the package with an empty
+CONTENTS file. This causes problems for other packages because they 
can't be properly buildlinked (or something like that?).

Debugging gives this:

Program received signal SIGSEGV, Segmentation fault.

#9  0x08049a9a in ___start ()

I have yet to understand why it bombs in pkgdb_store(). I found
#29894 which could perhaps be the same problem, even though I have
not seen any failing fprintf()'s here.

Anyone else seeing this? I have considered wiping my usr/pkg and
start over from scratch with freshly built packages, but I thought
it could be good to get to the bottom with this problem first, now 
that I have it easily reproducible.
