pkg_add hangs and consumes 100% CPU

["Sevan / Venture37" <venture37%gmail.com@localhost>]

Hi,
Trying to setup a bulkbuild environment using the
pkgsrc/mk/pbulk/pbulk.sh on Suse Linux 12 running on Power8. The
system hangs at the install stage of devel/ncurses and top shows
pkg_add using 100% CPU

=> Checking for missing run-time search paths in ncurses-5.9nb4
=> Checking for work-directory references in ncurses-5.9nb4
=> Creating binary package
/tmp/obj-pbulk/devel/ncurses/work/.packages/ncurses-5.9nb4.tgz
===> Install binary package of ncurses-5.9nb4

Attaching to the pkg_add pid with gdb, I see
(gdb) bt
#0  0x0000000010096650 in mpool_get ()

snippet of disassemble output from gdb:

If I bootstrap pkgsrc and attempt to install devel/ncurses manually,
things work as intended. Any pointers appreciated.
